<br>
I have a mythtv backend and two frontends - one being a VIA-based system<br>
running minimyth, and the other being my FC8 laptop (Dell 430 with<br>
i915_dri video card) with atrpm yum repo.<br>
<br>
Since upgrading all three to 0.21 (from 0.20), my FC8 laptop has been<br>
unusable as a MythTV frontend. The playback is atrocious. Stuttering,<br>
freezing, audio and video out of sync, etc. Under 0.20 it was<br>
rock-solid. This problem doesn't affect the minimyth frontend, and if I<br>
NFS mount the backend on the laptop and play recordings directly using<br>
xine or mplayer, they work just fine - so I know it's not a direct<br>
hardware problem.<br>
<br>
I get errors like the following when I try to play something under<br>
mythfrontend:<br>
<br>
NVP: Timed out waiting for free video buffers<br>
First A/V Sync reported error: Bad Context<br>
WriteAudio: buffer underrun<br>
NVP::AddAudioData():p1: Audio buffer overflow, audio data lost!<br>
<br>
I've tried a few different "TV Playback" settings, OpenGL vs none, and<br>
even threw out pulseaudio and went back to ALSA (happy with that<br>
decision anyway - more 3rd party apps work now). Games like OpenArena<br>
work just fine, so the video and audio "in general" are not the problem.<br>
<br>
Any ideas what magic wand I need to shake to fix this up? Damn annoying<br>
not being able to use myth from my laptop :-)<br>
<br>
Thanks!<br>
<br>
Jason<br>
