[mythtv-users] Playback problem using VDPAU and mythtv 0.22

[Indridi Bjornsson]

Hello fellow Myth users,

Been having lot of problems with playback, both with live tv and also
with video. My hardware is as follows:

Motherboard: GA-73PVM-S2H with NVIDIA GeForce 7100 / nForce 630i Chipset
Memory: 2 Gb
Processor: Pentium(R) Dual-Core, E5200, 2.50GHz
TV-Cards: 2 x Nova-T
Graphic Card: NVidia GeForce 8500 GT

I orginally installed Mythbuntu 8.10 and MythtTV 0.21 using the
onboard graphic card, but added the 8500 card when I started
experimenting with VDPAU. I installed Avenard 0.21 + vdpau early on
and since then I have been experiencing lot of playback problems. Been
trying different versions of NVIDIA drivers, different XOrg config
settings but with no luck.
Moved to trunk about a month ago trying different NVIDIA drivers and
different playback setup but again no luck :-(

Currently my system is unusable. I'm able to play some video but no HD
material or live-tv. Doesn't matter whether I'm using the onboard
graphic controller or the GeForce 8500 GT. I even tried replacing the
GeForce 8500 with GeForce N9400GT. I did make some difference but I
still got playback problems playing HD stuff.
I have been Googling a lot following up on errors in mythfrontend log,
trying out different settings and config and as I said with no luck
:-(

I decided to installing from scratch and see what happened. Had a
spare disk that I could use and installed MythBuntu 9.04 and
everything worked great, live TV, playing HD material, no complains in
the mythfrontend log (using -v playback). The playback profile was
CPU+. The NVIDIA driver version installed was 180.44. I then upgraded
to trunk and things started to get all wrong even live-tv didn't work
well. Added TripleBuffer and disabled Composite. Live-TV worked but
playing HD still caused the same problems, tearing and complaining.
I then installed the latest NVIDIA driver 190.36 and it didn't make
any difference, same problem when playing HD material. Changing the
playback profile to CPU+ playback didn't change anything, same
problems.

So what should I do? What is going on here? I should be able play HD
stuff on this hardware using the Internal player, right? Does VDPAU
suck or is there something wrong with my setup? Should I file this as
a bug?

Attached are configuration files and log from the newly installed setup.


Thanks,
Indridi
