[mythtv-users] Audio+video stutter after upgrade to Fedora 10+NVidia 180 on FX6200

[Niels Dybdahl]

Hi,

I have just upgraded from MythTV 0.20+Fedora 6+Nvidia ? to MythTV
0.21+Fedora 10+NVidia 180.51-1

Everything works except that the video and audio stutter so that it is
unwatchable.
- No stutter if I use a different PC to play the recording
- Stutter if I try to play a recording with mplayer -fs -vo xv . No error
messages from mplayer or mythtv that I have noticed.
- CPU goes close to 100% while playing with either mplayer or mythfrontend.

My GPU is a NVidia 6200 which worked fine on my old installation.
I have checked in the Xorg.0.log that it is the 180.51 driver that is
loaded:

  (II) NVIDIA dlloader X Driver  180.51  Thu Apr 16 19:08:39 PDT 2009
  (II) NVIDIA Unified Driver for all Supported NVIDIA GPUs

My best guess is that the Xv does not work correctly for some reason. I have
reused my xorg.conf from my old system. Should anything significant be
changed from F6 to F10?
Another guess is that the NVidia driver 180 does not work properly with a
FX6200 even though I have read that it should.
I have appended my xorg.conf

Does anyone have an idea what is going on?

Best regards
