 My setup:

 PassThruOutputDevice            ALSA:hw:0,0

 AggressiveSoundcardBuffer       0

 When playing a 720p mkv video with subtitles included, the audio does not
 work properly (ie - about 1/2s of audio plays for every 5-10s of video),
 but video is perfectly smooth. I get the following in the logs:

 2008-04-23 23:48:08.422 NVP: 1200 progressive frames seen.

 MKV's without subtitles work just fine.
