I used RipIt4Me and DVD Decrypter to save and ISO to my HD.
I assume Decrypter will indicate if it's a SL or DL ISO.
Should I buy -R or +R media?
Do I have to set a bit or change a book type to get the disc to play in stand-alone, portable or home DVD players?
When I made the ISO of The Pirates of the Caribean 2, Decrypter indicated it didn't have a country code and stated the ISO may not work if I did NOT select a country code. I chose the U.S. code.
BTW, the window to choose a country code always wanted to be BEHIND the main Decrypter screen. It was a Bi7ch to get it to the front for a split second to click "OK" before the main Decrypter window jumped to the front of the screen. Cancelling and moving the main window to one side of my screen didn't help. The Country Code Choice window ALWAYS opened in the center of the Main Decrypter window and imediately fell BEHIND it even though it was the ACTIVE window. Since it was the active window, I couldn't drag the main Decrypter window or click anything. You would think hitting the <Return> key would have entered the choice of the Country Code window but it didn't. I had to finagle bringing that window to the front with <Alt><Tab> with my cursor where I knew the "OK" button would be and quickly clicking before the main Decrypter window jumped to the front.
Your advice on media and getting a working back-up is greatly appreciated.
After I complete this project for my niece, I'd like to back-up some old TV series complete season sets I have to as few discs as possible.
