By far the weakest link in your proposed plan is the most critical component: the LD player. Your Sony is not nearly as well-regarded as just about any Pioneer machine. You've got almost everything else right, but the player's going to be the thing that limits how good your captures are.

The other thing that's going to hurt you is noise from the discs. I have all of the discs you show, and I can tell you right now they will benefit from TooT. That's why I got at least three copies of each movie (well, the 1995 THX ones, anyway).

If you really want to do this right, you've still got a bit of work to do!
