Basically, for your situation, there are two ways to go. First what version MPEG video are you trying to output? MPEG-1/2/4? If you have QuickTime Pro you can export to MPEG-1/2/4. Or if you don't try Super. It is a freeware multiformat video converter. It will let you transcode to MPEG/Flash Video/WMV/AVI/XviD/DivX/VOB/etc. You can also convert/transcode to PSP/iPod/3GP for PSP/iPod/cell phones.
