Why, oh, why can't I just get what I see in the preview window?

[Adobe Premiere filter] I have a screencast of a Powerpoint presentation and a webcam video of myself explaining the subject. Using Premiere Pro, I have combined both so that the webcam feed appears as a picture-in-picture in a corner while the presentation runs. However, despite everything looking fine on preview, when I attempt to export the file, the Powerpoint part plays about 10X faster than it should. Help?

I must admit to being a total Premiere newbie — this is my very first semi-serious video editing project. I have managed to figure out by myself what I expected to be the hard part (i.e. actually positioning and synchronizing both video clips), but now I am completely stumped at my inability to export what looks like a perfectly good result on preview. My Google-fu has totally failed me so far, so I'm hoping that the Hive Mind might have the answer.
As I said, the two video clips are correctly positioned and synchronised, and they play together perfectly fine on preview. However, when I attempt to export the file, the "main" video (i.e. the Powerpoint screencast) seems to play about ten times faster than the webcam PIP window. Obviously, this results in the two clips being spectacularly out of sync — so much that, in fact, the presentation is over after just 4 minutes, while the webcam keeps running for another half hour or so.
The video clips are both .avi encoded with Xvid. The screencast is 1280x720 @ 25 FPS, while the webcam feed is 640 x 480 @ 30 FPS. The clips were recorded, respectively, using Camstudio and Debut Video Capture. I am trying to get Premiere to export to H.264, but I seem to have the same issue regardless of which codec I choose for output, including uncompressed AVI.
Might one of the Premiere geniuses in the Hive Mind have any idea what might be causing this sort of behaviour?
Thanks in advance!
