OK, I understand what you are saying because nothing outputs through a budget
card.  What I meant to say is that a recording from a budget card and a
recording from a FF card both play the same when using a software decoder such
as xine.

ACK. I hope that someone who understands the mpegpes code in mplayer can shed
some light on this. What kind of repacking is mplayer doing that fixes this
problem.  It is definitely not transcoding the video.  All it is doing is
forwarding the video to the dvb card via mpegpes.
