I was just wondering if Dvd2dvdr can shrink the whole Dvd or just the movie?

As i have heard good things about this bit of software.

But i kinda like having the whole Dvd

Im using Dvd shrink at the mo & i think its brillent.
i always like to try out new bits of software...
Does any one out there, no what the problem is with Dvd2One freezing at certain parts of the film as i have read a lot about this happening
