I have some mpegs that have two channels to them (cantonese and mandarin) and i'm trying to put them onto a dvd. Everytime I convert with Ulead (which takes 10x longer then single channel) I only hear one of the audio channels when playing. Looking at the file sizes it doesn't seem to be correct either. Also when using ulead to convert the files, does the quality of the video seem to go down? I've used it to convert some things, and looking at it carefully the quality of the video seems to have gone down. Anyone have any suggestions, or settings that might help? Thanks
