Have you tried processing your mpeg with ProjectX before encoding? I've had 
great luck using ProjectX, mencoder, and avidemux2 on my ATSC mpeg2 files.

as for quality loss, YOU WILL ALWAYS GET QUALITY LOSS WHEN TRANSCODING. this 
is meant for the list, not just you. but I see it enough. your working with 
lossy formats and changing attributes about it, so you will always loose 
quality. Now, if your mpeg2 files meet the DVD standards, ProjectX can 
convert to an mpeg2-ps from an mpeg2-ts that should work for DVD's. it just 
remuxes the files without any transcoding.
