Hi moe2006....
Im not familiar with Nero, but I am familiar with dvdsanta...
The steps are so easy with it 1 2 3 and its done...
It will convert and burn many different file types...

The Demo version is a good one there are no time limits and it has all the functions of the paid version, it will however have demo across the top of the screen in the video output, but by zooming in it will dissapear... This is a link to the site...

To buy the software is also very cheap, half the price of Nero...

Dvdshrink will not decode files and neither will dvd dycrypter....
Those apps are mainly used to copy a purchased dvd to a blank dvd....
