There is an option inside of TMPEG plus when your going through the wizard to transcode an mpeg. You can choose at how many KB per second you want the video to be encoded at. I usually choose 3000 or 4000 depending on the size, but how does this relate to table top DVD players? Is there a certain range that most DVD players are used to and if so what is it?
Look at step 4/5, I don't change anything on this page except I use 50% for a two CD movie to fit one DVD ,and 33% for a 3 CD movie & etc... http://www.videohelp.com/tmpgencdvd.htm
