dvd compressing

ok so i just picked up the psp max media manager pro right. one of its features is it can convert TS files to MP4. my problem is the files are just too big. is there any possible way to compress MP4 files? or to just compress the TS or VOB files? any help appreciated!!

I'm not smart with videos, but I can tell you MP4 format is the most compressed format you'll get. However you could reduce the quality by opening it with a video editor and saving it with reduced quality, then converting it to MP4.

Btw, you could have always looked on Google to see how to convert TS format

heh sorry two rev after the vid finished converting i saw my half hour movie was only about 50 mb... the ts file started at like 2 gigs!!!! thanks though. i feel special.
