[mythtv-users] Choppy playback with PVR350 on Fedora Core 6

[Jeff Fisher]

Hi folks,

I currently have a machine running Fedora Core 5 w/ a PVR-350 and I'm 
having absolutely no problems with it when it comes to recording or 
playing back those recordings; however, the machine I setup for a friend 
is a totally different story. His machine is a similar hardware 
configuration to mine but instead of running Fedora Core 5, I decided to 
use Fedora Core 6. Basically, when watching live tv or watching a 
recording, the video is choppy and we did some testing to determine 
where the problem is and it seems to be when it is actually recording 
the show.

We recorded an episode of Law & Order and I copied it from the myth box 
to my computer and used mplayer to play it back and the playback was 
choppy just like when watched through mythfrontend. While myth is 
recording I have checked CPU usage, memory usage, I/O numbers, etc.. and 
everything looks to be fine.

Does anyone have any suggestions as to what we should try to resolve 
this or even try to just figure out what is causing the problem? I'm 
tempted to redo his machine and put Fedora Core 5 on it to see if that 
helps but that doesn't seem like a very good long-term solution :)

Here are some version numbers (myth was installed by following the 
Fedora Myth Howto):

ivtv-0.10.1-126
mythtv-0.20.1-156
kernel-2.6.20-1.2944

Thanks,
Jeff
