I think I've posted about this before but its really driving me crazy. I had hoped this was fixed in the latest release but seems not to be so. When I play back from the time line even with effects off and set to draft auto, the video starts dragging slower than the video. I've tried changing the Dynamic RAM from 0 to back where it is now 1024 with no affect. I've tried changing all the buffering options under Audio Device in preferences as well as Audio device type. I'm on Vista 64 but as others, running 9.0b in 32 because of plugins. Intel Core 2 Extreme CPU X96450 @ 3.00 GHz and 8 gigs of ram.
Anyone else getting this or got any other options that I may try. This has been happening for awhile now and really makes editing painful, let alone trying to show something to a client from the timeline.
