[mythtv-users] Upgraded to 0.21, video "stutters"

[Johnny Russ]

I had problems with video playback when I upgraded to 0.21. My problem 
sounded a little different, mine would just skip or hang in places. I 
found out that in 0.21 they changed the way the video is rendered. More 
CPU intensive methods are used by default. I had to go into TV settings 
-> Playback. There is a section that allows you to choose which playback 
method is used based on resolution, etc. I only have a P III at 1 GHz in 
my box so I had to switch mine from the new settings back to using XvMC 
and that got things working for me. I am not sure what settings would be 
appropriate for your box. I believe you can also try ivtv as the primary 
playback in the same dialog. Good luck.
