mkisofs fails to make DVD with DeVeDe 2.1

[Duncan Lithgow]

mkisofs version: unknown
DeVeDe version: 2.1 alfa 2
Kernel 2.6.20-2-generic

(same bug against DeVeDe 2.8 and Kernel 2.6.17-10-generic is bug#77248 )

Step to reproduce in DeVeDe:
* Select 'Video DVD' from the first menu.
* Under 'Files' add two or more mpeg 2 files from Kino (to test menu structure)
* Accept all default options, set action to 'Create an ISO or BIN/CUE image' and select 'forward'
* Accept default name and location (make sure there is enough space)
* "Job done! Elapsed time: 0:0:42" But movie.iso is 0 kB

Command line output is attached.
XML file for parsing by DVDAuthor (?) attached.
