Hi all,

at least some progress.

I tried to extract, compression set to off and also disabling the "remove ... 
protection" options as best as I could, however, the result is quite playable 
with mplayer.
Also, it is not a hardware but a software issue, as my notebook is able to 
Shrink the file, but not play it with mplayer / xine(kaffeine) / VLC player. 
It doesn't play with powerdvd as well and I think, the Dell machine uses 
WinDVD. Also, the default Apple MacOS X player does play quite fine.

Any ideas on how to provide an unchanged stream?

Thanks for your efforts,
Jonathan

PS.: I started to communicate with universal pictures about this issue. They 
indirectly confirmed, it is some form of copy protection, still I didn't get 
more than a more or less automatic reply yet. It's kind of funny to see 
DVDShrink to work out of the box (not even possible to generate a 
non-functioning copy) but many DVD playing programs to fail. It is kind of 
ironic, that my only possibility to arrive with a viewable DVD at this point 
seems to be to make an illegal copy of the DVD.
