Just a quick note in case it helps...
As I posted in another thread, I tend to collect these to try & always have a more-or-less current version on hand -- Hollywood updates their DRM with almost every major movie release, & that may mean a software update's needed too. I tried it with a rather difficult & very recent DVD & it seemed to work fine. It didn't take a full minute to scan the disc & display the info. OTOH the DVD I tried has fake playlists, so I'd have to watch it all the way through before I could say it definitely worked the way it's supposed to.
