Problem with cs4/choppy export

[green thumb]

I just made the switch to cs4, and so far it's hating me!

Here's the deal:
I'm importing the video clip, pretty sure it's .mov, 720 24p, and i'm pretty sure all the settings are matching that.

Even with no effects applied, if i try to export (using the render queue) the finished product skips several frames and is the exact opposite of the look I'm going for

Any idea why I can't get a smooth export? If there are any details I'm leaving out, I'll gladly post 'em up!

Sub-question:
In premiere cs4, in the timeline I'll right click a clip and click "replace with after effects composition"
AE opens, the comp comes up, I'll make my changes. In this case a ramp slow mo. Either nothing happens at all, or the slow mo will show up but the audio remains the same. Driving me crazy! And what's worse is I'm sure I'm just missing something incredibly simple.

Anyway,
Thanks in advance:beer:

What format are you exporting? Are you sure it's not your computer or hard drive choking? i.e. a playback issue? e.g. if you export an lossless/uncompressed stream. What are your computer specs ?

For #2, did you forget to save the comp? or are you saying "nothing happens" within AE?
