I have a PVR-250 and a bttv card in my system.  The "waiting for data"
problems occur with the PVR-250 card while watching LiveTV for me,
but I suppose it could still be a bttv driver problem.  I'm using
Mandrake 9.1 with the bttv drivers compiled in by Mandrake.  I'll
try messing with the ivtv and bttv drivers both.  I've suspected a
problem with one or both of the drivers anyway.
