[MPlayer-users] Cache doesn't refill

Hmm...are you sure the card is supplying the data fast enough then?  If
you record the dvb to disk and after a couple of seconds play back the
file while it's recording, does mplayer 'catch up' and quit when it
reaches the end of the file?  If so, mplayer is playing the data too
quickly (e.g. I would expect this behaviour if you were playing a 25fps
movie at 30fps.)

If it only delays the problem, it sounds like mplayer can't get the data
fast enough for some reason.  Although the mplayer cache appears strange
and it never wants to keep up, it does seem pretty reliable and I've
always eventually found out that something else was to blame for the
buffer underruns.

Cheers,
Adam.
