i'm trying to split a dual layer dvd into 2 single layer disks to keep the quality. when i analyzed the dvd, the estimated input and output sizes of the disk were disk 1: 4+ gb, disk 2: 3+ gb. which was cool. but after actually ouputting the dvd, disk 2's output size came out to be 5+ gb. so i couldnt burn disk 2. disk 1 was fine and came out close to what the output size was suppose to be. be disk 2 came out about 2 gigs more than what it should've. now i cant burn it. any ideas on what could be going on? thanks a lot.
