I decided to back up my Futurama collection (all 4 volumes) Volumes 1,2 and 3 (all 11 discs) duplicated without a hitch ... However, the last 2 discs of volume 4 have given me nothing but trouble! They play fine on my set top DVD players and on my set top DVD recorder, but they refuse to play on my computer. I have been using DVD Decrypter and DVD Shrink and then burning with Decrypter on all of the other discs ... the last 2 discs like I said, won't even play on my computer and DVD Decrypter says "Device Not Ready (Unable to Recover TOC) when I put either disc 3 or 4 in ... Anyone have any suggestions??
