-Fixed bugs in title/chapter handling once more, especially for size 

detection and location of main movie.

-Support for multitrack DVD : now the stream is given to input as it has
to be ; however, all the tracks are displayed one after the other ; I
think we need to decode navigation ES to choose the track

-Fixed behaviour at end of device.
