i`m looking for a guide to convert an xvid file 512x384 with mpeg layer 3 sound to dvd-r at the best quality to fit on half a dvd. I am currently using tmpgenc encorder to convert to dvd resolution of 720x576 and pcm wave audio, the video bitrate i use is a cbr of 3950. Has anyone got a guide out there or a better way to do this please.
