That's the option I'm using.

They are Mandriva 2005, running stock kernels of 2.6.11 & 2.6.12 kernels,
the same Nvidia driver, downloaded from their web site.
The Nvidia driver always loads the XvMC library
I think; I've never loaded any specific package other than these.
Remember, both machines worked fine with XvMC for over a year (used daily) on
0.18.1 or before.  The Myth upgrade has been the only change.
