You have a GeForce4 ti4600?      Those cards do not have full MPEG2
acceleration.   If I remember correctly, they support motion compensation,
but not iDCT (iDCT is the bulk of the CPU offload).

The GeForce4 MX cards, GeForce FX, and newer cards all support full iDCT+MC.

I had a GeForce4 4200 a few years ago,  I moved to a GeForce4 MX for the
MPEG2 accel, and later upgraded to an FX 5200.    You lose 3D performance,
but that's not a factor in HTPC usage..
