For a while now I have been using DVDshrink in combination with Nero 6 to back up my DVDs with great success. I'd like to say thanks to the guys on this forum re DVDshrink and particularly Doom9's useful how to guide for DVD shrink.

The other day I came across a problem with a particular DVD, when I try and re-author the DVD I am unable to select and move the chapters I want even though the chapters are shown on the screen as per normal. I thought it might have been a problem with my DVD drive, however I can play the DVD without any problems using Power DVD.

The only obvious difference that I have found between this particular DVD and others that I have burnt successfully is that this one contains a DVDrom as a special feature and has a macro-vision copyright protection stamp on it.
Any advise on how to solve this?
