[mythtv-users] stuttering video and audio mythbuntu14.01 on atom w nvidia and vdpau

Mon Apr 28 11:07:49 UTC 2014

The problem seems the same with all VDPAU profiles. This log was captured
by watching live SD TV, VDPAU slim profile, with alsa default audio.

Both the audio and the video were very stuttery and slow. 1/2 speed or less.

Cheers
