Back before I knew much about backing up movies, I used InstantCopy--the Disk Quality scan below was burned on either an NEC 1100, or a Plextor 708UF (can't remember which).
Since I've been learning a ton of great info here, I've gone back and started scanning some of these old disks. What a shock! The scan you see here is actually one of the better ones.
I stopped using InstantCopy a long time ago, and now use Decrypter and Shrink solely. The reason I'm posting this here, rather than on Recording Software, is that I am curios what it is that produces a curve like I'm seeing here. Every single one of the disks I burned back then, and just scanned now, looks basically like this. I realize now that InstantCopy is pretty much a p.o.s., and doubt I'd ever touch it again, but just for my own curiosity, what produces a graph like this?
And I have played all these old disks in my older Panasonic set-top player--which use to be the only way I could judge if a disk was good or not. I thought they were fine. Stupid me.
How could a disk that scans this bad, even play?
