Hi,
I have one commercial DVD in my collection that makes Transcode go nuts.
When I try to probe it, Transcode returns complete nonsense:
tcprobe -i /dev/dvd

Transcode sees only one title on this DVD, attempts to probe title 2, 3,
and so on fail. Accessing the individual chapters using tccat fails too.
Both by set-top DVD player and Xine play the DVD perfectly. While playing
the DVD, I found out the structure of the DVD, which is like so:
Disk contains 2 menus:
* Main menu, which has 4 entries:
1: 8 chapters ~60 minutes
2: 2 chapters ~10 minutes
3: 3 chapters ~18 minutes
4: SUBMENU
* Submenu, which has two entries:
1: 1 chapter, ~3 minutes
2: 6 chapters, ~14 minutes
All other DVD titles from my collection return correct information when
Transcode probes them, so this must be a bug in the way Transcode
interprets the structure of the disk.
I have spoken to the author of 'libdvdread', and he verified that the
output of libdvdread for this DVD is correct.
I can attach the IFO files of the DVD, as well as the libdvdread dump of
the IFO files, if that is of any use for finding the problem.
By the way, I use Transcode version 1.0.2.
Cheers,
Dik
