I am having a problem with importing .mp4 files into Premiere Elements 11 which were made in iMovie. When I drag the .mp4 files onto the timeline in Premiere Elements 11, the audio track seems to compress and does not coincide with the video track. When I play the original mp4 file from Finder, it plays fine. The audio is in sync with the video. Any suggestions as to how to solve this?
MP4 is a wrapper, what is inside YOUR wrapper - Exactly what is INSIDE the video you are editing?

Does your video use a VARIABLE Frame Rate or a Constant Frame Rate?
Premiere Elements 11 Mac
If you exported your video file (.mp4) from iMovie, I would expect that your frame rate is constant and not variable. And, from what I have
read, iMovie has problems with imports that have variable frame rate. So import or export iMovie, I see this factor as a non issue for Premiere Elements in this case.
