I saw something similar last night. The encoding would be going
along with effective 'q' around 5 or so and then zoom up to 30 or 40
for a little while and then go back down. This would happen at
apparently random intervals thru the encoding process.

If ~1.5GB of NTSC-DV data would be useful to you let me know and
I'll put it up for FTP for you. I think you might want something a
little more than a few seconds for testing (to see the rise/fall
cycles).
I think it would be possible to manufacture examples - decode one of
your DVDs and then re-encode it.
Cheers,
Steven Schultz
