Hi, I'm trying to play/ copy a DVD I own, onto a DVD-R. But when I put the DVD into the DVD player... One in this comp, and one in another, it wont even play? It's the Buffy season 2 set I'm trying to duplicate. The second disk, One of the epsidoes stops working halfway through, and freezes my comp.. Plays perfectly fine in my DVD player though, no skipping or nothing. Then the Fourth disk.. wont even play. In my Pioneer A05, it doesnt load at all. in my Reg DVD drive, it loads, but I cant browse or see files, or play the DVD... it says the disk is unformatted, or in an unsupported format. This is a brand new season DVD set, All the other disks copied fine.. but this one wont, anyone got any ideas? Thanks.
