Is it possible that VDR is not dropping the bad frames properly, thus causing dvbplayer.c to struggle when processing/forwarding the video to the FF DVB card? This is the command used when playing back DVB compliant VDR recordings to a FF card with mplayer: mplayer -vo mpegpes -ao mpegpes -framedrop -cache 4096 -slave -nolirc -quiet 001.vdr Notice that "-framedrop" is added to the command line. I wonder if that is the reason why mplayer is "immune" to the a/v desync problem. Best Regards.
