A person on this forum told me about IFO files and BUP, saying to open the highest KB IFO folder to play the movie. But my Windows Media Player will not open IFO (or BUP) files. ONLY VOB files. While I opened the Video_TS (VOB file) for one copied movie - which worked perfectly - when I try to do it for the other copied movie (Memoirs of a Geisha, in case it makes a difference) it will only run the previews. When it gets to the main menu (where you hit "play movie") it stops.
As an FYI, I only have Windows Media Player for XP (which wouldn't work tonight until I downloaded a driver - NVIDIA is the one I chose, but it only has a 30 day free trial)
