[dvd::rip] DVD.iso

[Jenda Vancura <jendavancura@xxxxxxxxx>]

Hello,

I am having problems transcoding a .iso DVD image to avi format - and 
I've done the same before without trouble. I have several isos, and 
neither will even read the title list. These are the errors:
"
An internal exception was thrown!
The error message was:

Can't use an undefined value as a HASH reference at 
/usr/share/perl5/Video/DVDRip/GUI/Project/TitleTab.pm line 716.
"
"
Can't determine number of titles.
Please put the DVD in your drive.
tcprobe output was:

[tcprobe] Digital Video (NTSC)
[tcprobe] summary for /home/jenda/Cinema/xXx.iso, (*) = not default, 0 =

import frame size: -g 720x480 [720x576] (*)

  no audio track: use "null" import module for audio
DVDRIP_SUCCESS

What can I do to fix this?

Thanks
