And framerate if you want to use a ntsc file for pal project or vice versa. You can always convert them to the other format (change res and framerate of the vid and speed up/slow down the audio) or use the corresponding form the mini-dvd. Well, I can't find it now but there _was_ a minidvd for boh pal and ntsc clips, the pal feeatured the usual Dolby trailers in anamorphic format (that's cool) and the Broadway trailer (the one with the helicopter) was the older one which is quite a rare found (as the Train long version).
