Default Re: 190.40 fatal mythtv video freeze

On the face of it, this appears to be a MythTV error. All of the VDPAU functions appear to complete without returning any error, and the sequence they're being called in looks reasonable. For some reason, MythTV decides to stop playback, I'm assuming due to these messages:

2009-10-22 20:00:07.305 WriteAudio: buffer underrun

2009-10-22 20:00:08.905 NVP: Prebuffer wait timed out 10 times.

2009-10-22 20:00:23.313 NVP: Prebuffer wait timed out 100 times.

2009-10-22 20:00:23.313 NVP, Error: Timed out waiting for prebuffering too long. Exiting..


(I don't know what causes those, since I'm not familiar with MythTV internals)

and then gracefully cleans up VDPAU, which also appears to succeed. I'd suggest asking on the MythTV forums how to track this down (or pointing one of the MythTV people who hang out here at this thread).
