I found an interesting thread about mplayer and a52 CRC errors: http://pchdtv.com/forum/viewtopic.php?t=1048&postdays=0&postorder=asc&start=84 (Be warned, the above thread contains mplayer developer bashing.) Anyway, I've found a way that appears to have mplayer behave a bit nicer in the face of apparently mplayer induced "CRC errors": $ cp .azap/channels.conf .mplayer/channels.conf $ mplayer dvb://WFOO-HD -framedrop -cache 8192 mplayer still shows CRC errors, but it doesn't bomb out. Do not use something like the following: $ azap -r WFOO-HD $ cat /dev/dvb/adapter0/dvr0 | mplayer - or $ azap -r WFOO-HD $ mplayer /dev/dvb/adapter0/dvr0 as mplayer dies after the CRC error.
