Jan Schmidt 3c1a1dfec5 resindvd: Fiddle with segment handling for DVD. 
Clarify some of the terms used, and make sure to extend the
stop time when the position moves past the end of the current
segment (as for still frames, for example).

Also, make sure to reset the position value of the segment the
demuxer outputs when collecting a seamless segment.
