Greetings! The members of this forum have been of invaluable service in making my CloneDVD usage a successful experience. I've tried to backup several films onto a blank Double Layer (DL) DVD. In each case, I receive a "Source Data Too Large" error message. I'm selecting "DL" in CloneDVD2 and receive a "100%" quality display. The film and its extras are about 2 hours in length. My computer is 3-4 years old. How do I know if its drive is even capable of making dual-layer copies? It's a Toshiba/Samsung: TSSTCORP CD/DVDW TS-H552B GA04 / OEM Code GA I went to Samsung's website, but was unable to determine from there whether it's DL capable. I believe I'm signed up for automatic upgrades of the writer via the Samsung website--but I'm not certain of this. Does anyone believe they know the answer? Thanks!
