I haven't upgraded AE to the CS3 version so can't give you any direct
comment on RAM preview differences. Adobe essentially broke their end
of the codec in the other CS3 products so that older AVI's captured with
a Matrox DigiSuite system that are larger that 1 Gb get truncated. With
that in mind, there may be other formats & codecs that CS3 treats
differently.

Check where you've told AE to go for it's temp files. If they're being
written to the same external drive, try switching to the internal drive,
or vice versa. Also try 1/2 or 1/3 rez for the preview. Got the latest
video drivers for your display card?

Also if you haven't, I'd suggest going to Creative Cow
http://www.creativecow.net and posting your question there. You'll get
much more response there than here in a video NG.
