[ATrpms-users] Gigabyte Nforc3 + x86_64 + PVR150 + FC6 no worky

[cromworshipper-atrpms at yahoo.com]

I had a MythTV setup working well with FC4 i386.  I did a clean install of
FC6 x86_64 which went reasonably well, but with one major problem.  I'm using
the atrpms repository for nvidia driver, ivtv driver, and mythtv.

The recorded video plays fine for a few seconds and then flickers or tears
very badly.  It's different for different channels, some play with only a bit
of tearing/flickering while others are much worse.  

I've turned of APIC.  I've looked at the verbose IVTV output. I don't
understand /proc/interrupts so I've pasted it below.  

What could it possibly be?  This exact same setup worked very well with FC4
i386, and I kept it up to date with yum.  If I can't figure this out, I'll
have to try FC6 i386.

Suggestions, even google terms would be helpful, thanks.

John
