Let me guess?  PVR 250 card?  Used to work, but maybe you upgraded the ivtv
driver to something newer than ck114k?  If so then I've got the same problem.
 Ivtv driver ck114k works fine in myth, any driver after that plays live TV
and records video at super speed.  Makes recordings funny, and live TV just
plain painful.  I understand it has something to do with the audio format but
no idea what.  I also undertand that it affects very few of us, as most people
are using the newer drivers with no hint of problems.  Outside of myth I find
the newer ivtv drivers both capture video and play through mplayer at normal
speeds just fine.  Only in Myth does the problem appear.

Currently trying to sort it out on the ivtv list.  

Of course, we may have differnent problems ;)


Nothing goes to waste when Little Fish are near!
