I've been working on taking MPEG2 files and creating DVDs from them. There is a command line tool known simply as dvdauthor. Someone has produced a GUI front end for it called GUI for dvdauthor. It does a fairly good job.
This is it people. The one stop shop for everything and anything related to CD sized disks that hold video data: DVDs, VCDs, SVCDs. Included are discussions on trans-coding from different formats, players, burners, capture cards, software, media quality.
