Just to remind folks of an earlier post of mine, I bought a new Sony DVD +/- R RW player at Sears for $100 and it plays every disk I have tried. Problems I was attributing to DVD2One, Shrink, DVDXCopy, etc. were really the player I was using even though it was a high end player when I bought it just a year and a half ago.
If you want real results and not problems caused by a player you thought was adequate, upgrade your living room player, you may see that some disks you thought were coasters weren't after all.
Example: Insomnia with Robin Williams, for some reason I tried copying it from 2 different source disks. Both times the copy became unplayable halfway through. Luckily I didn't throw them away. After I got the new player they played fine.
