[QUOTE="Scythe42, post: 507139, member: 95833"] Basically just some different codecs. Gave them a try though: same issue. Audio will drift over time for x264 content and SPDIF passthru over a HDMI connection when 23.976Hz or 24Hz is selected (method of selection doesn't make a difference). Some files are worse than others though for yet unknown reasons. I also did a trial with Win 7 RTM: The EVR renderer behaves at 24p very similar to VMR under Vista. Meaning that audio will not drift over time. At least not with a test movie I can reproduce the behavior under Vista right away. There is a fixed delay (roughly 50ms on my rig) though under Win 7, that doesn't happen at 60Hz. Skipping forwards and backwards also behaves like VMR under Vista.
