I personally like dvdsanta, it has a free trial version that never runs out, it just has a demo message at the bottom of the screen and all you have to do is zoom in a frame or two with your dvd's remote control and it's gone..
I used it for ages, I have the full version now and it's excellent (it's cheap as well)..
This is a guide to dvdsanta...
