Guys, thanks a lot for your help and ideas. After reading and digesting your replies I’ve gone round and round on this. Some updates:
First of all it finally dawned on me that regardless of how good my DVD-R’s look when played on the DVP-NS975V (which does indeed upres to 1080-i, and whose circuitry I’m convinced really does minimize motion and crosshatch artifacts when playing my travel disks), I can’t make “finished” DVD’s in 1080i anyway. So the best I can do is find the cleanest way possible to capture the raw video, make my edited DVD’s, and then play them on the 975 and hen I want to watch them on my HD set. This was probably so obvious to you guys that you didn’t bother to mention it, but it wasn’t obvious to me. (I’m an audio guy who is relatively new to video.)
I got hold of a Pioneer PRV-9000 DVD-R (with DV out) and tried going DV in to the Canopus 110 but unfortunately, the Pioneer only played about half of my disks, it wouldn’t recognize the others. I have found that this is the case with some DVD players — they will only play about half of my disks, with no apparent rhyme or reason. Other decks play them all with no problem. Too bad, oh well.
So, with that possibility out the window, so I think I’ll go ahead and try the DVDXDV route. I don’t even have a DVD drive for my Mac yet, so getting one (and making sure that it really plays all my disks) will be the first step. If it does, I’ll go ahead and try DVDXDV. It seems better than trying to round up all the expensive hardware I would need to capture the disks via a digital video cable.
Thanks again for the help, it is greatly appreciated. I’ll keep you posted.
