Well, that’ll be my next option I suppose. Disc 3 (just the film itself with no fluff this time) is in process as we speak. Fingers crossed!
JEDIT:
Hooray! Dunno what was causing problems with the intro videos, and while it would’ve been cool to have those, I’m just glad I don’t have a third coaster. Looks like I’ll just keep it simple in the future when muxing iso files.
If you weren’t doing so already, I would try multiAVCHD next time for multiple clips. But it’s possible one wasn’t compliant (multi should tell you and give the option of reencoding, though).
