mpv/libmpdemux/dvb_tune.c
arpi d891bc11cc this patch fixes 
1)  some bugs introduced in the tuner autodetection and in the channel-parsing functions,
3) retries reading when the mplayer/mencoder don't read fast enough (sooner it exited)
but especially
4) makes the stream compliant with the new, modular stream api (the one
currently in CVS is not and is totally unreachable).
[and maybe more, next time please include cvslog in patch! -- A'rpi]
