[Bug 131220] making dvd video iso image doesn't seem to work

[John McPherson]

Public bug reported:

Binary package hint: genisoimage

ii  genisoimage    1.1.2-1        Creates ISO-9660 CD-ROM filesystem images
ii  cdrkit-doc     1.1.2-1        Documentation for the cdrkit package suite
on feisty x86.

I can't for the life of me figure out how to create a dvd video ISO.
Either the functionality isn't working as expected, or the program needs
to give better debugging messages.

genisoimage: Unable to make a DVD-Video image.
Possible reasons:
  - VIDEO_TS subdirectory was not found on specified location
  - VIDEO_TS has invalid contents

ok, presumably that doesn't work because it wants to put all the files
into the / of the image, instead of a VIDEO_TS subdir.

Possible reasons:

now it says it can't find VIDEO_TS.IFO ?? But if I run this again
without -dvd-video, it puts the VIDEO_TS.IFO file into the VIDEO_TS
directory....


attempt 3:

genisoimage: Unable to make a DVD-Video image.
Possible reasons:
  - VIDEO_TS subdirectory was not found on specified location
  - VIDEO_TS has invalid contents


now it is trying to stat an empty file [strace shows stat64("", 0x...)], and it complains that it can't open a device?!! why is it trying to open a device?

Could the documentation please be updated to let users know exactly what
is required to make a dvd video iso, or even better the error message
from genisoimage should say exactly what the problem is instead of a
generic "invalid contents" message.
