Apparently this was needed for good DVD playback.
This demuxer has been removed in 1fde09db6f. All code added comes
from the revision before that. Some other bits have been removed in
later commits, and are added back as well.
Usage of memalign() is replaced by av_malloc(). As far as I can tell,
this memory is never free'd or reallocated, so no calls to av_free()
have been added.
The code re-added to video.c is plain horrible, full of code
duplication, full of demuxer/codecs specifics, but apparently needed.
Unrelated to re-adding the demuxer, re-add one codepath for
DEMUXER_TYPE_TV, which was accidentally removed in the same commit
demux_mpg was removed.
The closed captions decoder is not re-added.
