I backed up a dvd using the following method and programs:

1. backed up on hd using lates dvd decryptor (3.6 I think)
2. resized with dvd2one 1.1.2
3. burned with latest nero (5.5.20 I think)

All this produced a good, clean backup but with one problem. Whenever I fast forward the film at whatever speed (2x, 4x, 20x, etc.), I couldn't press play and get the movie start playing from that point. I fast forward, press play, then it would freeze for about 3 seconds and them resume playing but it would revert to the beginning of that chapter and play from there. Although I haven't done this for as long as some of you, I have backed up about 7 movies prior to this without this problem. The only things I did different was upgrade to the latest version of dvd decryptor and dvd2one. Much appreciation to anyone who can help.
