FWIW, in my opinion, a two-frame difference only makes a difference for English audio tracks. Differences that small are only really noticeable with lip sync (and barely noticeable at that). Since dubs don't really match lip sync 100% anyway, I'd say two frames is within the range of acceptable error for dubs, and two frames delayed is also more natural than two frames advanced.

We also need to remember to check the 16mm mono mix while we're checking English audio tracks.

Harmy--I thought your video was already based on the NTSC frames. It uses PAL frames? Yeah, trimming video seems the best choice if it's PAL frames.
