I was playing around with my 8.10 hybrid core trying to remove unused entries in the computing menu. I must have done too good of a job because now the installed programs and bookmarks in the computing menu are both empty. How can I get it back to the default configuration?

Thank you

tschack909's response below solved the problem.

I will add, clicking on "TV" at the top of media allows me to watch TV just fine.

That's a bit different than the problem that I'm having. I cannot play live or recorded shows in the MythTV player.

Try doing this in the MythTV frontend:
"Utilities / Setup" - "Setup" - "TV Settings" - "Playback"  and uncheck "Always stream recordings from the backend"

I thought that fixed the problem for me but it only fixed it when I started MythTV from KDE...although MythTV from KDE didn't have any sound. I still have the same problem when choosing TV from media under LMCE. I'm wondering if it could be a problem with the sound card.

It still does not appear to be related to the HVR-2250. I removed the HVR-2250, installed a new DVB (950Q) and had the exact same problem. The problem only happens when playing live tv or videos back through the MythTV player. I am able to record shows and play them back through other players just fine. How can I see the mythtv front end logs? Don't I need to run it from the terminal with the -l option? If so, can someone tell be the directory and command to do that? I tried mythtvfrontend -l and I had no luck.

I have a NVIDIA 8200 on the motherboard. What's the likelihood that that is the problem? Could it be the sound card?

Thank you for your help!

i see that there was already a template for the 950Q, but it didn't seem to make mine work PnP. I edited the template and removed the serial number. The machine saw the DVB, but kept on looping and asking me if I want to use the DVB.

What error do you get on-screen when mythtv freezes?

There is no on-screen error. MythTV just locks and I have to have LMCE turn it "off" to get control back.

Have you looked at both the frontend and backebd logs in /var/log/mythtv/?

Yes, I have checked the backend log and it says: http://pastebin.com/f9A4R7w9
I don't know where the frontend log is. I only see mythbackend.log and mythfilldatabase.log is that directory.

When you playback the recorded video, does it play ok or does it skip and jump on playback?

So far, my tests when playing back the recorded videos through LMCE work without a problem. Playing back the same video through the MythTV player has the same problem as when playing live TV. That's what makes me think it's a problem with the LMCE player. I would think that properly setting up the setup/TV settings/playback/profile would fix it, but so far, no luck.

Is your card analogue or DVB?

DVB. Dual tuner. I won't hide the fact that this tuner (HVR-2250) has had many problems with MythTV (or linux for that matter) but since I can record fine and playback in another player, that makes me feel that the problem is not necessarily with the tuner.

I'm still trying to troubleshoot the issue I'm having with the player in MythTV freezing during playback. Since I can record videos and play them back through the LMCE player, I'm thinking it's not a problem with my HVR-2250. I set the vmalloc=192M as suggested http://www.mythtv.org/wiki/Common_Problem:_vmalloc_too_small and I've tried of settings in the playback profile in the frontend settings of MythTV. This issue is really driving me crazy. Which logs should I be looking at and where do I find them?

I'm starting to feel more confident that the problem is with the video playback under MythTV. I was able to have MythTV record a show and I was able to playback the video under media/video of LMCE but not through the MythTV recordings.

At the suggestion on the chat room, I tried setting the playback profile (under MythTV Frontend/Setup/TV Settings/Playback) to VDPAU slim. I was then informed that my 8200 does not support VDPAU. I tried a few other playback profile settings and I get the same brief bit of sound and video.

I did upgrade Firefox about a week ago on the orbiter in my office using the directions previously supplied.  So far I have not found any issue with it.

I will upgrade my daughters media director and post my results.

I look forward to hearing about your results. I greatly appreciate your step by step instructions. I was trying the Chrome route because I was afraid of breaking something when trying to upgrade Firefox.

When I try to install Chrome I get "status: Error: Dependency is not satisfiable: liabasound2". When I try "sudo apt-get install libasound2" I am told that it's already the latest version. So I did more searching and I found the suggestion to "apt-get install libnss3-1d libnss3-1d-dbg libnss3-dev libnss3-0d libnss3-tools". I did that, packages installed/upgrades but still no luck installing chrome.

Any thoughts?

Thank you for the info. I don't know how I missed KDE desktop at the top of the menu. 

So i D/Led Chrome and I opened it up in the package installer and now it won't install because off

status: Error: Dependency is not satisfiable: liabasound2

Isn't ALSA part of that package and already on the system? What should I do now?

Now that Pandora upgraded to their new interface, I can no logger get it working. They require Firefox 3.6.3 or >. How do i upgrade Firefox? Or should/could I install a newer version of Firefox and keep the exiting one there as well? I tried to figure it out on my own but I don't know how to install without a package manager. If this something that I could go into Kbuntu interface to do? If so, how to I get to the Kbuntu screen?

Sorry for all of the newbie questions. I did try to figure it out on my own, but I have been just banging my head against the wall.

When I enter MythTV I get a split second of sound and video just before it freezes.

I have not previously gotten MythTV to run. Recently I did get Myth TV backend installed (my sources.list was out of date) and now the system sees my Hauppauge 2250 and allows me to configure it in the media setup. I tried to get it working by populating the channels with my SchedulesDirect account, but I guess that Media setup didn't complete the import because I kept getting an error when I went into MythTV that there were no channels setup. I then went into Myth backend Setup and scanned for channels. Even in MythTV backend setup, when I chose to import the channel listings, it did nothing. I know the schedules direct account is correct because I see listings in my program guide. Any thoughts on why I'm not able to just import the list of channels?

Leaving the importing of channels aside, I did do a scan and add the channels that way. It's not nearly as clean, but it does at least let me get to the next step. The problem now is that when I start MythTV the screen freezes after a split second. LMCE isn't locked because I can still go and exit MythTV. I did a lot of searching and it looks like this might be a problem with a video drivers. I verified xorg.conf and I am using NVIDIA for the display. cat /proc/driver/nvidia/version shows that I have:

Code:

NVRM version: NVIDIA UNIX x86 Kernel Module  195.36.15  Thu Mar 11 21:41:46 PST 2010
GCC version:  gcc version 4.3.2 (Ubuntu 4.3.2-1ubuntu12)

Am I going down the right path to correct the freezing problem? Any thoughts on how to get it working?

Thank you!

Alternatively you can locate your MD behind the TV and do the switching by controlling the TV's input via RS232. You then need more cables because you still need to get the audio signals back from the MD/TV to the AV Amp and you still need to control the AV amp too so an additional rs232 control capability is needed. All in all this is messier to be honest.

Thank you for taking the time to put together such a detailed response.

You mentioned an AV amp in each option. Since it's not going to be used as a theater setup, I was planning on using the TV's internal speakers. If I only need a MD in this setup (since I don't use cable boxes and I don't need a DVD), are there good VESA mount options that would just be between the mount and the TV?

The TV doesn't have an RS232 input. Can I control it using USB? It has two USB inputs. Or do I need to use IrDA from the MD?

* The other approach is to locate all of the system equipment centrally at the 'Hub' of the system and use HDMI-CAT5 baluns to transmit the video (and possibly audio) to the TV screens in each room. You will also in this type of system need to have long speaker cables run to each room from the 'Hub' and possibly long rs232 or in-room IP based rs232 controllers - either of which will require more CAT5 to be run to each room. The advantage of this topology is that everything is out of the room apart from the TV & the speaker systems and so there is zero clutter, all cables can be neatly run in-wall/ceiling and there is no issue of fan noise or other 'noise' from the system components as they are all remote from the room.

My system (what little of it there is so far) is actually just a hybrid core in the basement. I have wired the home with Cat6 and there are speakers wires going from the core to in-wall speakers in the Living and Family rooms. So far all we have used the system is for zWave (over 20 devices) and playing audio/Pandora to the in-wall speakers. I'm anxious to get MythTV part working within LMCE so can decommission my standalone Mythbuntu and cleanup the gnarly setup we have in the master bedroom (so far the only TV in the home)

The setup I'm trying to get done will likely be a 32" or 40" TV on a wall in the family room. Ideally, it would go on the wall facing towards the family room from the kitchen and would be able to extend out and turn 180 degrees to face into the kitchen. If I pull that one off, my wife will be REALLY happy.

My wife has given me permission to get a new TV, provided that In finally get LMCE running seamlessly with the TV. The TV will be wall mounted and it will need to look "pretty" with no cables and boxes visible around the TV. Basically she wants it too look like a framed painting hanging on the wall.

• What the best way to mount a TV and MD on the wall? Are there and compatible VESA mount systems that work well as MDs? I'm a bit concerned with heat.
• The TVs that we are looking at (Samsung LEDs) have USB 2.0 inputs. Can the TVs be controlled by the MDs through USB?
• What do people do with wall mount TVs if they need to connect things like Blu ray or cable boxes to them?

After i get the TV and MD sorted out I will need to get her Galaxy S phone setup as an orbiter. I'll also need to finally get my Hauppauge 2250 working with MythTV or break down and buy a dual tuner card that is proved and handles clear QAM

Thank you for your assistance.

I'm running the August 5th snapshot and while sitting at my core I see a box pop up in the upper left hand corder that displays a number of "failed to get" messages including failed to get Mythtv-backend. What am I doing wrong?
