You may use the av_pes2any utility (part of the DVB driver archive) to
demultiplex the pva stream. In my place it did not work reliable: The
Mpeg 1 layer 2 audio frames had additional 14 Bytes at the end -
apparently exta bytes are in the pva stream. Video demultiplexing caused
some segmentation faults. Basically video only elementary streams should
playblack with mtv (a linux mpeg player) but it didn't work either.
The PVA-Fileformat specification can be obtained diretly from the
Technotrend webserver:
