It's been a while since I had the 8600GS in my MythTV testbox but I tested it again just now and it does Temporal Spatial 2X (Advanced 2X in mythtv) for SD material displayed in 1920x1080 without any problem.
Also tested on mpeg2 50 Hz interlaced material.

I guess GPU clock speed and memory clock speed can make a difference?

This is the result from my 8400GS and 9500GT:
