The last time I made a dvd with DVDStyler on 07-10-2012 everything was going OK.
Doing the same today (after ?? updates) generating a .iso is again no problem.
Opening the .iso in VLC or (after burning a DVD) using a real DVD-player given the following result:
The menu with the items is shown.
However it is not possible to select and thus starting one of the movies on the DVD.
In short: It is a useless DVD.
I also have a Clonezilla-PCLOS-12-10-2012 image.
Putting this image back on the appropriate partition and installing dvdstyler-2.3-1pclos2012
there is no problem with DVDStyler.
However after a 131 package update (kde-4.9.2 + ??) the problem has also come to this version.
A check of the above mentioned dvdstyler (+ deps) shows that they have not been changed during the update.
This is as far as my current search goes in tracking down which package is responsible for this misbehavior.
Anybody any idea how to progress now
