The PVA* files are test files for my PVA demuxer. The ones with "BROKEN" at the end manifest the problems I wrote about in the mail. The others play fine. I noticed an A-V delay at the beginning of every file, that goes away after a few seconds. I guess it is because of the stream format from the DVB board. The "jumpiness" of the Audio and Video PTSs comes from the stream itself, and varies from channel to channel. Matteo Giani
