Hello All,
I have scanned the forum and wiki and I have found helpful information about hardware. However, I have yet to figure out an anwer to the best complete hardware list for a hybrid box.
What I would like to know is, is there a list of recommended hardware for building a comlete hybrid box that is known to work together out of the box. For example, motherboard "X", processor "Y", video card "V", Tuner "A", and sound card "S" is a complete package that works with LMCE and are compatable with each other. I have had problems in the past when I was building my Myth TV box when video card "nV" is not compatable with tuner card "H" and you have to jump through hoops to correct the memory allocation.
Any help or constructive advice is appreciated.

Basically, there is a ton of information in the wiki about hardware. It is pretty daunting to try to sort through it all to build a basic system. I was wanting to know if there is a recommended hardware comfiguration that just works (motherboard, US terrestrial tuner card, graphics card, processor, nic, USB-UIRT, etc). I am new to Linux and LMCE and I am learning a ton as I play with it. I'm not doing home automation just yet. I am just looking to replace my MythTV box with something a little more robust. I don't have the specs with me so I can't tell you what it has in it right now. Just suffice to say that it took me a while to get it running because of hardware conflicts. For example (MythTV), my nVidia driver broke my tuner card until I reallocated memory. I have read things on this forum about on-board nics not working on MB brand "X". The list goes on. like I said, I am new and I learn by breaking and fixing but I need it to work first.
All that to say, is there a list of LMCE compatable hardware that works well together. A shopping list of sorts I suppose.
Thanks,
M.

Why don't we start with your preferred form factor? microATX, full ATX, mini ITX?
Do you have a case already? Perhaps you want to use your existing MythTV case?
Cheers,

If you want pre-configured systems, you can get them from www.lmcecompatible.com ... funds there go towards helping us devs. If you are in the UK, you can get a Cascade or Dianemo system.
With that said, we have been keeping lists of motherboards and things known to work, the unfortunate reality is that new products always come out and supplant the old ones, and in the desktop computing world, this happens at an alarming rate.
But, once you get past the motherboard, using two NICs, an NVIDIA GPU, and supported tuners, will get you what you need. If you can, even...spring the extra cost for server motherboard and memory...the reliability you will gain will be priceless.

Everything is on the table. I am not going to convert my current MythTV box as I originally tried loading 8.10 on it (before beta was released). It never worked and would do different things everytime I tried to install (we won't go into detail as I am not looking to author a book).
Form factor could be anything that works. It seems from the research that I have done is that a seperate video card works better than an onboard one. It also seems that there are more ATX boards w/o onboard video than there are micro ATX. Since I will be buying all the components new, that there are no limits.
But it seems that ATX is the better option. Am I off base on this one?

PS. I am still searching the forum and wiki while we are talking. I know how annoying it can be to restate what has already been said. Sometimes you just need help pulling it all together. And I appreciate your help. I am happy to read an earlier post if you have any that you can direct me to.

I'm in the US. I would prefer not to get a pre-configured system as there is a certain amount of enjoyment that goes into building. I would be willing to buy whatever is available from the LMCE Store since it helps y'all out.

I've been looking at the motherboards on the wiki...there is just so many of them. It's a little overwhelming.

So far, this is what I have gathered from the wiki and forum.
Tuner - HD 5500
GPU - any recent nVidia that has is compatable with my display
Remote - USB-UIRT (do the gyro remotes with built in infrared work with these?)
Motherboard - ?????
Processor - ????
Good so far?
-
I would honestly recommend an HDHomeRun, if you want a ClearQAM tuner...otherwise, get a Hauppauge HD-PVR and attach to your cable box's component out.
The Gyro remotes have their own transceiver and do not use the USB UIRT. However, the UIRT will prove instrumental in IR control of your A/V gear.

I don't have cable or satellite. I am getting my HD OTA. Currently I have a Hauppauge WinTV-HVR-1600 (collecting dust) and a WinTV-HVR-2250 currently installed in my MythTV box. I like the single cable/dual tuner of the 2250. I don't like the fact that the IR remote doesn't work. It came with a MS Media Center remote. I like the way this page <http://wiki.linuxmce.org/index.php/Capture_Cards> is set up. It just doesn't have any real information on those two cards. It seems to like the 5500.
Since i am not using cable or satellite, should I still use an external box like the HD Homerun? Or should I stick with an internal card.
The price for a homerun seems reasonable.

Mandingo has written templates for the two tuner cards that you have. They should be found and configured appropriately.

Processor - If it's a hybrid which you intend on turning into a standalone core at a later date with lots of MDs, get a half decent dual core. Don't go mad; LMCE needs only modest hardware. If it's a hybrid that you intend on turning into an MD at a later date, a single core processor will probably do you. Again, it does not need to be powerful, if it is specifically for LMCE don't spend too much money. The crappy computer in my workshop must be 7 or 8 years old, and it works fine (as an MD!).
Motherboard - If it's a hybrid/core, might want to go fullATX for the extra PCI slots (remember you need a second NIC when it comes to booting MDs). If it's going to turned into an MD, microATX should be fine. Or, consider getting a miniITX board, which has processor built in (just make sure you get an "ion" one - this is nVidia). Obviously you will be very limited on PCI slots, but miniITX boards make fantastic MDs in my opinion.
-
Okay...great...recap. This will be Hybrid that could possibly be converted to a core later.
Full ATX MB (just about any new one will work, ASUS or Gigabit?), seperate nVidia GPU (probably a GeForce 9 series or later (I need component out for now), modest dual-core processor.
Back to tuners. Since this is a new build (I don't plan on using anything that I currently own) would I be better off with Silicondust, pcHDTV, or Hauppauge?
Are there any ASUS of Gigabit MB that I need to avoid becuase of known issues such as onboard audio or nic not working properly?

Again, if you want my advice..you'll do good to base your hybrid on a server motherboard. Your chance of both hardware compatibility and reliability go up immensely. Keep in mind, this machine needs to run 24-7.

That's right, you said that already (I didn't ignore you, I just forgot) . I don't know anything about server MB vs plain ole everyday MB. I will do some research on this and not clutter your forum with that..yet. :-)
Any advice on the Silicondust vs Hauppauge vs pdHDTV question for tuner cards. Like I said, this is a new build so my concern is performace as well as compatability. It seems that all of there are plug-n-play in your system so the question is more about performance.

Server motherboards do seem awfully expensive, but of course you get what you pay for. I for one (and I'm sure plenty of others) have been getting on OK with "normal" motherboards (although my core motherboard did fry the other week.... ahem). Personally I would definitely consider getting a server motherboard in the future, if only because Thom has recommended it... the difference is that I have been playing with LMCE for several years, and have fully accepted it into my life! Maybe you do not want to spend that much of your hard-earned to begin with.
Now you've narrowed it down a bit (we're going with full ATX right?), maybe have another look at the wiki, keep newegg open on another tab, and see what's available. I would say that ASUS or Gigabit were reasonable brands. Post back with some motherboards that you like the look of. One thing I had to keep in mind when buying a full ATX mobo was the number of PCI slots vs PCIe slots. I needed at least 3 PCI slots (two tuners and once NIC). You might want to consider this also, as it keeps more options open to you in the future.
Cheers,
Matt.

I've looked at newegg and saw that the server MB all seem to have built in video. This was an issue when I was building my MythTV. It was a micro ATX and had a built in Intel GPU. The options in the bios were limited to putting it as a second priority to the nVidia card (9 series I think). I couldn't disable the onboard GPU completely. This worked fine with Myth but seemed to be problematic with LMCE. I couldn't use the onboard GPU with either because of perfomance issues. I really needed the more robust nVidia performance. Could this be an issue with the server MB as well or do I just need to pay attention to the onboard GPU specs. I didn't see one with onboard nVidia.

That surprises me; I thought you could disable onboard graphics completely and just tell it to "look" at the PCIe slot or whatever and that was that. Are you sure it was properly disabled?
Sorry, you said you had an issue building your MythTV, but then you said it worked fine with Myth and caused problems with LMCE - could you clarify please?

Sorry about the confusion. I had memory problems with setting up my MythTV. It was a Hauppauge issue when you installed the latest nVidia drivers and also tried to get component out. I had to edit the grub to reaollocate memory on boot up so the the nVidia drivers had room to load. Once I fixed that in Myth, it was fine. That was the only real issue but it was well documented.
The LMCE issue was because the onboard Intel GPU wasn't cutting it, when I looked in the BIOS to try to bypass it, it only allowed me to put the onboard as a secondary priority and not disable it completely. This particular problem didn't seem to cause an issue with MythTV but LMCE didn't like it. I even connected a monitor to both outputs just to see what it was doing. If the onboard GPU was set to the primary, it would install and load just fine. I just had perfomance issues with HD and the nVidia card had no output at all. If I set the nVidia card as the primary, then I would get to the video wizard and and it would just hang. I couldn't seem to get it to show on the screen. I know that there are instructions for hitting the right keys in the right order to get a screen to show up but they didn't seem to work. I could dig through my docs and find the MB model and also tell you what it says about the video options for the BIOS.

I really don't know what to say, I never knew that could happen.
If you want to be absolutely sure that you are not going to be affected by this issue, get either a motherboard with no onboard graphics, or one with onboard graphics that you can use (i.e. nVidia). Are you dead set on a server motherboard?
-
No, I am not dead set on a server MB. Thom mentioned it so I thought it was worth looking into. I completely respect Thom's opinion but when I noticed that I wasn't finding a server MB that didn't have an onboard GPU, I started backing away from them. This was based on my experience with my MSI G62-75221X4-Q13. That is the MB in my MythTV. In the advanced BIOS features of the utility, it has "Primary Graphic's Adapter". It doesn't even list in the book what the options are or what they do. It's not a great resource. I think that I will go with a full ATX Asus or gigabit w/o onboard graphics. Does LMCE support nVidia VDPAU? I know that Linux and MythTV do.
I'm still looking for advice on the SiliconDust vs Hauppauge vs pcHDTV capture devices. Any thoughts?

I would honestly recommend an HDHomeRun, if you want a ClearQAM tuner...otherwise, get a Hauppauge HD-PVR and attach to your cable box's component out.
The Gyro remotes have their own transceiver and do not use the USB UIRT. However, the UIRT will prove instrumental in IR control of your A/V gear.
-Thom
If you don't have a cable box with component, only HDMI, I have HEARD that HD Fury2 or better still, 3 will remove the HDCP giving you a clean signal for storage on the HD-PVR b=via component.
Anyone have any other info on that product, or know anyone that has tried it, speak up.
