Welcome here!

You're starting with V8 DVD?
Instead of MPEG-2, why not start with lossless X9 capture?
I'ts available on Usenet.

To one of your questions, V8 (and X9 and JSC in general) are missing quite a few frames compared to GOUT.
Surrounding reel changeovers, and also mid-reel.
The missing frame numbers are documented in my IVTC script for X9 cap, which is also on usenet.

I just lost my Usenet access yesterday, actually. I have X0's original captures (35GB of lossless Huffyuv AVIs). Will those work OK?
