Greetings,

I've installed (auto install) KnoppMyth R4 and it is working, but I have poor video output - Basketball games impossible to watch and I also have muted (lower volume) on the Live TV than the media player. I have tried every combination of the Myth settings I can find. Also, I have tried, with no success, to update Myth to either 0.13 or 0.14 using the debs. I have put the sources in /etc/apt/sources.list but get package not found errors when I try to apt-get install mythdvd-i686_0.14-1_i386.deb ...

I am apathetic to upgrades if I can get the video working and get a little more volume out of the current build. I have litterally been reading these, the alsa, ivtv, nvidia and myth forums for days, but no joy. I will say that this is working better than the Fedora Core 1 install I was beating my head against a wall with for the past month (locked up all the time), in at least it can run for 24 hours in Live TV without crashing, but...

Any help would be appricaiated.

Here is what I have:

SOYO Dragon Lite (VIA KT333) MoBo
Athlon 1.3 GHz T-Bird
256 MB PC2100
On-Board C-Media 8738 4-channel audio
NVidia GeForce 4 MX 400 64 MB w/ TV out
WinTV PVR-250
Maxtor 160 GB 7200 RPM 8MB HDD
Intel 10/100 PRO NIC

Here is what I installed:
-------------------------------------------------------------------------------------
KnoppMyth Auto Install mode w/ defaults all the way.
install-i686-l
install-nvidia.sh
Fixed the Zaplistings.pm file (added the space)
Edited the XF86Config-4 file as shown below
Edited .fvwm2rc to exec mythfrontend rather than KnoppMyth-run

Here is my XF86Config-4

If you have edited /etc/apt/sources.list, then you need to apt-get update followed by apt-get install mythtv-i686-lirc(since that is what you have installed on R4).

I apologize, ( you can never be detailed enough on this stuff can you )

I did apt-get update ( some of them fail as has been pointed out elsewhere )

Now, are you saying that I DON'T run an install against all the debs listed in your announcement, but just the "mthtv-i686-lirc_0.14-1_i386.deb"? AND do you think it will help the video performance?

Sorry, that is most likely a dumb question, but this is my first Linux project.

No, I listed mythtv-i686-lirc because that is all you had listed as the deb you are trying to get... NOTE:I said apt-get install mythtv-i686-lirc NOT apt-get install mythtv-i686-lirc-0.14 -1_i386.deb. apt-get what you want. Actually since you have a GeFORCE four, you want to apt-get install mythtv-i686-lirc-xvmc. Have you installed the nVidia drivers? If you have not, that is probably the reason for the performance issues. You'll want to install them first before getting and trying the new debs.

Ahhh, gotcha. I will do that right now. I have run the NVidia driver script, which I assume is the 4363 driver.

BTW, you are da man when it comes to quick replys! Thanks for your help and I'll post when I am done.

I try my best...
You're welcome.

Okay, got everything but the mythdvd. I am not real brave so when it gave me an error, I left it alone as this is not something I will use for a while.

BUT...when I try to start the backend, I get this:

mythbackend: error while loading shared libraries: libXvMCNVIDIA_dynamic.so.1: cannot open shared object file: No such file or directory

From reading other posts, I assume this means that there are kernel modules not loaded for the nVidia card. I did an apt-cache search for nvidia, but I'm not sure what I should load. I am also taking if for granted that the install-nvidia.sh must have missed something and this may be the root of my performance issues.

Odd about libXvMC... Might I suggest:
As root in a terminal not X:
/etc/init.d/gdm stop
wget http://download.nvidia.com/XFree86/Linu ... 0-4363.run
export IGNORE_CC_MISMATCH=1
sh NVIDIA-Linux-x86-1.0-4363.run
accept the agreement and have it install...
Once complete
/etc/init.d/gdm start

And your paypal account is??

I'm at work (shhh) but I know the backend and frontend are up. Once I get home I'll see if the performance is better.

Thanks again for your help!

You're welcome.

Well, I had to do a couple of other things as I still had the performance (screen update and muffled sound) issues. I had to install KDE and uncheck the use HW MPEG-2 in the Myth 0.14 config. Everything is working great now though. Smooth as silk video, good audio, no timing issues, lockups or blank recordings!

I know, your gonna flip about KDE, but I had read somewhere (cant remember where) that the KDE desktop manager was better with Myth than the rest.

I'll post the whole installation in the Tier 2 forum in a few minutes.

Thanks again!!!

Well hate to tell you but kde was not the solution. The solution was unchecking use hardware mpeg2 decoder, as you don't have a hardware mpeg2 decoder. The pvr250 is a hardware mpeg2 encoder. That would have explained your playback problems. My only question is was that box checked by default, or had you checked it sometime during the setup, because I know it was not the default when I did my install, and should not be the default, cause most people will not have mpeg2 decoders.

First, yes I knew the checkbox was the video performance fix (after trial/error), but I didn't get my audio up to full volume until I installed KDE.

And I don't know if it was default. I've become so brain dead with this whole project - been trying to get a stable, usable MythTV system up for over a month. But Hey, brightside is I DID IT, and Billy G has nothing to do with it

Just did a complete reinstall to make sure its clean and DID NOT install KDE .

I did notice however that the hardware decode is checked on 0.14 by default. Maybe something in the order I am doing things.
