Only BS.Player Pro can also play DVD's "DVD-style" (using DVD-menu etc. on the basis of the VIDEO_TS.IFO), but BS.Player Free is only able to play the individual VOB-files. So you simply have to select the correct VOB files. (So e.g. start with VTS_01_1.VOB
(... VTS_01_2.VOB ... VTS_01_3.VOB ...) instead of with VTS_01_0.VOB). If you put these
VOB's in a playlist, the entire movie will be shown in one go (as one would expect).
Look at the size of the VOB-files; those of the actual movie usually have a size of 1.048.404 kB, mostly except for the last part which may be smaller.
(As may be expected encrypted DVD's may still be a problem. The application "DVD Decrypter" could maybe help there.)
