I ripped a DVD using DVD Shrink and it created an ISO file on my hard drive, Size: 4.35 GB. I opened the ISO file in NTI CD & DVD Maker Gold but when i pressed Ok for it to burn to disc it said it completed in 24 seconds which obviously means it didnt copy the file to the dvd disc at all. Why is it doing this? I formatted the DVD disc before attempting to burn it.
