What should I do with movies that are not mod16 (between 706 and 718 pixels)?
I've searched, but couldn't find the actual answer to what's the best thing to do:

Encode at non-mod16?
Encode with black bars?
Resize up?
Resize down?

Don't encode with black bars, it wastes bitrate at edges. Emcoding at non-mod16 is better than that. And about resizing... it's purely your choice. Probably it'd be optimal, but resizing slowes down.

Funky trick: crop so that overall dimensions are within +/-4 [+/-8] from a mod16 size, then resize only the outmost 16-thick [32-thick] borders. The small squeeze/stretch on the outmost borders usualy isn't noticeable, and the inner part of the frame stays completely untouched. ;)

Interesting appropach. I wonder if the transition won't be more noticeable than the whole wrong AR though..
And there is always option c: crop what you need, resize to mod16, and set the resize flag for correct AR in the container.

I would suggest that you don't encode non-mod16 if you plan to include subtitles, as directvobsub has a nasty bug with non-mod16 video.
