Hello,
I currently have an LCD TV hooked up to an antenna and it gets both anaolog and digital signals just fine. I also have the option on the TV to select either analog or digital to switch between the two. Of course digital is needed for HD.
Will my current setup still give me the digital signal if I run it through a linuxMCE box using a Hauppauge WinTV-PVR-150 MCE TV card and an nvidia 6200 chipset for a video card (DVI out).
Thank you.

What we do is have an aerial splitter/amplifier ahead of the Core and any other equipment that needs to take the TV aerial feed. So that might be in our case here in the uk 3 x Happauage Nova-T500 plus the normal analog TV tuner in the TV. So we have a 4-6 way splitter/amplifier to ahead of the T500's and the TV's aerial inputs.
Not quite sure if I understand that. I'm expecting the digital signal going into the TV card to be a digital signal coming out of the video cards DVI output. Or at least I hope so.
I'm currently only getting analog TV out using VGA, but that would make sense.
Hauppauge 150-MCE
This Hauppauge WinTV product has only an analog broadcast tuner and will require a converter box after February 17, 2009 to receive over-the-air broadcasts with an antenna in the United States because of the transition to digital broadcasting in North America. Analog only TV receivers will continue to work as before with cable TV and satellite TV receivers, plus other video devices such as camcorders and VCRs.
For more information, visit the U.S. FCC website on the digital TV transition at www.dtv.gov If you have any questions on which Hauppauge models support digital TV reception, please contact us at sales@hauppauge.com
Thanx for that info.
If I'm reading that right, no digital signal will go through the 150.
I'm a bit confused by this, how does anyone watch TV without a digital signal, or is this just a cheap card?
I've got an email into Haupauge to see what cards will support it. Does anyone know if any of the the currently supported cards can handle a digital signal?
I think you are confused by the use of the words digital and analog. The digital or analog signal going into the tuner card has nothing to do with the vga/dvi hookup you will use. That is all processed inside the computer and sent as video over the video connections. ATSC is the new digital standard of over the air signals for TV. No ATSC signal will be received/recognized by the 150. NTSC is the old standard that uses analog signals. That is the only signal that will be received by the 150. Yes, there is no HD broadcast over the old NTSC standard. I hope that helps.

The recommended solution for capturing digital TV is the hdhomerun (http://www.silicondust.com/wiki/products/hdhomerun).
Also, the Hauppauge 1800 supports ATSC but there are no linux drivers for it and no current plans to have any Linux support. Many people recommend the HD HomeRun by Silicon Dust. http://www.silicondust.com/ (http://www.silicondust.com/)
Yes, it's making sense now, thank you.
Now the bigger problem, Hauppauge's line of cards that support a digitial signal are these
WinTV-HVR-1250
WinTV-HVR-1500
WinTV-HVR-1600
WinTV-HVR-1800
None of which are listed as working with linuxMCE. The 1600 is the only PCI version, so I'm limited here. Does anyone know if that card will work with linuxMCE?
its worth trying. heres some stuff on it.

if that isnt something you can do, its possible someone else here will be able to help. right now it doesnt support ATSC through those drivers. hopefully it will soon. best bet is probably still the HD HomeRun.
I think that I can answer this. I also have a lcd with dual Qam (digital) and analog tuner, yet only one coax input. If i put an antenna I receive 20+ Digital channels ( 8 hd) but no CBS (chicago land signal issue). If i plug into my wall with basic cable and NO box, i receive 78 analoge channels plus all of the local hd and digital channels (including cbs, channels 100+) since Comcast relays the locals over the wire.
Now if i wanted to record or watch both in LMCE 'PVR i'd need a winttv 150 for the first 78 channels plus a digital tuner such as hd homerun to allow for recording and distributed viewing in other rooms. The hdhomerun which is a dual qam that would allow dual digital or hd recordings or viewings at the same time. I'd need two winttv 150's or 1 wintv 500 to get that dual capability for the analog channels. The hdhomerun also would alow for an antenna to receive the over the air digital and hd local's as an alternative to a local cable company relaying the local's
Now either the hdhome run or the wintv's input can be "split" and ran directly to my LCD for viewing, but that wouldn't allow for recording or distributing with out the appropriate analog or digital tuners or both tuners. Happauge does make a 1600 series tuner that is a dual analoge and digital (qaM ) in one card , but not yet supported in linux. if it was supported it wouldn't allow dual recording or recording and watching of 2 analog or 2 digital channel similtaniously, you'd need two 1600's for that, but the one 1600 will allow for a distributed watch or record of both 1 analog and one digital channel at the same time.
hope that helps. Shaun
looks like 4 others replied while I was typing,
Great info guys, thanx.
If I'm understanding correctly, the HDhomerun would not go through the LMCE and directly to my TV. So I would need to switch inputs on my TV to watch TV (no RS232 on my TV), losing the main purpose of a media center.
Maybe I'll give the 1600 a shot.
no the hd homerun does go through linuxmce.
OK, did my hdhomerun research now. I see that LMCE will detect it as a network device. So, is it safe to say there is no need for a TV card if using hdhomerun? Unless I want an analog input?
huh....i didnt realize that it only did ATSC. you could always use a splitter (you may want something to amplify the signal if its being split) and use both an hd home run and the 150. the 150 would give you the analog (NTSC) you want and the home run will give you the digital (ATSC). using the hd home run would not require another card if all you wanted was the ATSC format of over the air signals.
Thanx for all the help guys, I think I got it straightened out.
I'm going to see if I can get my hands on a WinTV-HVR 1600 tonight at a local store, if I can't get that to fly it looks like it's hdhomerun.
This is getting expensive :o

You have an aerial feed that carries both analog & digital transmissions. If you hook up the aerial to your 150 card you will send the analog signal to that cards analog tuner (as thats all it has)... what comes out of you video cards DVI connector is a digital or analog video signal... it might be a TV program or whatever you have chose to display on the screen ie a DVD or the KDE desktop. To get digital TV from your aerial feed you need a Digital TV card in your Core that has a digital TV tuner in it that is suitable for North American digital transmissions.
the hdhomerun is equivilant to a tv card, yes you are correct, no need for an additional card inless you want analog. The ideal here is to have all your channels weater analoge or dgital are both go through the LMCE and not have to switch the inputs on you tv and be able to record or rewind any thing that you watch.

You will have a much more reliable setup if you use a PVR-150/250/500/USB2 for analogue, and an HDHomeRun for HD. Trust me on this, I've been through it. If you skimp here, you will experience loads of pain.
