Hi there. I have been struggling for a month or so to make a video from loads of M2TS and converted DV files (350 all together) and get final video edited in FCP to a DVD, but the quality of the video is rubbish even on my 22" screen. What I do first is I convert M2TS files to a MOV in PAVTUBE (720x556 Pal, 48Hz, Apple PAL-DV-there are a lots of options there) which takes ages. Then I convert them in MPEG Streamclip again to a Quicktime so I dont have to render video in Final cut every 5 minutes. After editing I convert whole video to a Quick time for a DVD PRO Then video is rubbish. I definitely dont get codex.
