hello,
after switching from ae cs4 (on winXP 32bit) to cs5.5 (on win7 64bit) on the same pc, im having this problem:
when i start playback/ram preview even in a comp with just white solid, the playhead/cti/current time indicator red line is moving in a jerky way. The Info panel is showing that its being played in realtime and when i add footage, the video is being played smoothly as well, yet the playhead jumps.
heres a video of it:

(Tried AE with default settings, tried playing around with some of the settings which i thought that could possibly affect this, opengl etc. The OS installation is fairly clean, tried disabling non critical processes. hw: q6600@3.6, p5e64ws evo, 4gig, hd4870 512)
Any tips are welcome
