mplayer expects video in mpeg-ps/pes format.
mplayer cannot play audio-only files except some special formats like .mp3
.ogg, .wav and .wma

teh problem is that you need double demuxing
1. demux .pva to mpeg-es video and mpeg-pes audio
2. demux mpeg-pes audio

Albeu implemented such thing, for the ogg-in-avi thing, but i don't really
know how does it work, anyway it should be easy to implement.
At first step the mpeg demuxer should be extended to allow audio-only.
or you just can implement a demuxer which does the mpeg pes->es conversion
so you can avoid this mess with multiple demuxers.
