I burned the BDMV & Certificate folders with ImgBurn to a BD-25 then played it on my panasonic DMP-BD60.

The first thing I noticed was that it asked me if I wanted to play AVCHD video files or Picture files, which is strange for a blu-ray disc. After selecting AVCHD, the disc played the animated menus fine and I could select the audio or scenes select sub menus, however after selecting a scene the player would freeze for a few seconds before playing the Trailer! Starting again at the main menu the movie played from the beginning when I pressed play, but like Matt_Stevens I couldn't ff, rw scan or chapter forward.

The other thing I noticed was that the commentaries were not selectable from the audio menu and I couldn't find how to play the trailer, even though it did play inadvertently.

After looking at the profile level maybe it's because it's 4.1 and my player prefers 4.0 which seems to be the default setting in multiAVCHD.

As for the movie itself, this is definitely the best version out there and head & shoulders above my Region B blu-ray, many thanks.
