I'm ripping Spider-Man 3 right now. Will let you know how the whole process went.
Addendum:
About an hour later I have a rip of Spiderman 3. I had already done a TMDB lookup on the disc, so I couldn't verify whether MC just copied that metadata to the rip, or actually looked it up for me again. It plays flawlessly, as does the disc. (I only tried this 'new' feature of MC yesterday!)
There are a few extraneous files in the designated Rip folder that I don't want to keep. If I delete them, will MC have any trouble playing the rip from the index file? While I'm at it, I think I just wish to keep the main m2ts file, and perhaps one or two of the trailers. I think I'm just going to tag these separately and discard the BDMV folder structure for this movie at least.
Thanks for the feature.
