lsmod shows agpgart using nvidia, why would it do so if there's no AGP
interaction? I am not claiming to know the answer or questioning your
statement, I guess I am saying, why is there AGP stuff there at all?
The only nVidia thing is my video card, did its driver load AGP stuff
even though the card is PCI Express?

I am running OpenSUSE 11. The MythTV stuff comes from the Packman repositories
http://packman.links2linux.org/package/mythtv/
Currently running: MythTV 0.21-13

The only difference of possible significance is my Composite is
disabled, yours is enabled.

I'll play around some more tonight...
