Well it seems I spoke too soon, had only upgraded a few days before!

I'm seeing glitches on some bluray rip playback 1080p24 mkv and some subtle av sync slips in 1080i25 h264 recordings, I think I will be dusting off my GT220 shortly.

Agreed but across the 60hz world people are used to watching movies on TV with 3:2 pulldown, so I guess if they can get used to and ignore that mess they can easily ignore the more subtle motion glitches.
