Okay.
Change to the "tree" view in mediainfo.
I think the most useful info is giong to be the actual transcode, not the vobs.
In the folders for the Encore project, look for Sources -> Transcodes and then the file at issue. You want the m2v file to look at with mediainfo.
If you still have the automatic transcoded file and a new one, that is what I was looking for. If not, we can go with the vobs.
