Quality is my first requirement as well as 100% reliability. Backing up the movie is what I'm after as thats what I watch 99.999% of the time off a DVD. I use DVD Decrypter, DVD2SVCD w/ CCE, author in Maestro & burn with Nero. Always the best, always works
But I'm sure with the original DVD X Copy, then DVD2One, then InstantCopy 7, then DVD95Copy and finally DVD Shrink, I'm sure there is a product to suit everyones need.
