Suddenly I have a problem on my standalone DVD. The situation is like this:

I have for a while been making backup's of my movies for my standalone DVD (Philips DVD711) using Smartripper and IfoEdit.

Trying to backup Monsters Inc. and Peter Pan - return to Neverland I have problems with the backup.
On my standalone plays it recognise the disk (Imation DVD+RW) as a DVD-disk but it will not play it, it says the disk has No Chapters. But on my PC it all works fine with right language, all chapters and so on.
It is not the disk (If I copy an old backup to the disk It all works fine).
