Welcome to BC.
I don't think Apple supports MPEG. Lord knows I've tried everything I can think of to import MPEG 2 into iDVD, and iMovie.
But I use Toast Titanium 7 to export video and convert it other formats on the Mac.

Exporting Video
Toast can convert video files to a variety of different types and export to your hard disk.
To export video:
1 Click the Video tab at the top of the Toast window.
2 Click the Formats tab in the left drawer and choose DVD-Video.
3 Drag and drop video files into the Content Area from your hard disk or the Media Browser.
To use the Media Browser, click the Media tab in the left drawer. Choose Movies to browse your Movies folder and choose DVD to browse DVD-Video discs and VIDEO_TS folders. See Using the Media Browser. You can also use the "+" button at the bottom of the Toast window to add files.
You can add any QuickTime supported video files, such as DV, AVI, MOV, HDV (1080i/720p), and MPEG4. You can also add files that QuickTime doesn't support such as iMovie HD projects, MPEG-2, VOB and DivX.
4 Select the video(s) you want to export.
5 Click Export at the bottom of the Toast window, or choose Disc > Export Video.
