WHY doesn´t last file with Re-author of DVD schrink works???

[Johny1800]

I am trying to make a backup of my series Friends. And i want to put 9 chapters (from a total of 2 DVDs) on 1 DVD (The total size is 4.2GB).

The problem is that you can´t go to the last chapter/file. My dvd player goes into a kind of clickingsound mode.

I then put only 6 episodes on the disk, but still the same problem.

I am more thinking of that ot is a DVD-Shrink problem.

Does anybody has had something similar?

Or can anybody advice me another program so I can combine diferent DVD´s in 1 DVD.

Many thanks,

Johny
