[mythtv-users] WinTV (bttv) and PVR150 (ivtv) apparent conflict

[Ryan Steffes]

I posted this question in more detail on the ivtv list, but the mythtv
list gets far more traffic so I hope no one minds if I toss it out
here.  I'm running myth on a 2.6.8-10mdk kernel.  I've got a WinTVFM
card and just bought a brand new PVR150 MCE.  From what I can tell,
bttv and ivtv don't exactly play nicely with one another.

My bttv card only works properly if I rename the msp3400 module that
came with ivtv.  I can get the ivtv to seem to load properly with no
error messages that jump out at me, but it doesn't DO anything.  I'm
thinking this may be due to not having it's own modules.

Has anyone gotten this combination to work, and what did you have to
do?  I can upgrade to 2.6.11 if needed.
