I think your problem is really the source file, not the exporting.
Convert the source file to DV-AVI first, using mpegstreamclip or virtualdubmod.
Edit the DV-AVI, not the mpeg, and I think you will notice lots of difference, in more than just the exports.
Premiere is primarily a DV-AVI editor and has issues with some mpeg files, working with DV-AVI files will solve many problems.
