Chips,

You would be so much happier in the long run to use this as your opportunity to learn
Final Cut. Here's the work sequence I would follow.

1) Export your iMovie project to tape.

2) Capture live from tape into Final Cut as one reel.

3) Drop the footage into the canvas window.

<<<<<<You must use a TV monitor for this next step. It is impossible to sync correctly
watching playback on the Mac computer screen. >>>>>

4) Start playback of the sequence. At any point the sync drift becomes noticible, use
the razor tool to cut the audio tracks. Then slide the part on the right as many frames
as you need to (either way) for audio to line up again.

5) When the 53 min reel looks good, you may want to add audio crossfades at the cut
points to soften the rough edges. Another trick is to cut and paste ambient sound where
it is needed.

6) Add chapter marks where you want the DVD to have them.

7) Mixdown the audio (always the last step before export) If you change ANYTHING, do it
again.

8) Export as a Final Cut Movie

9) Open iDVD, import your movie and build whatever menus you need

10) Burn a perfectly synced project
