I've been looking for a program that can do dual-layer burning because I'd rather keep my collectors edition Miyazaki DVDs (the ones in a case that looks like >this<) as untouched as possible but without messing with their format... so I found >this<. Nifty little thing, just hit a button and it does it for you. Backed up my entire collection in about 5 minutes and put the DVDs into storage.
Just thought I'd share, took me way too many DVD-ROMs to find something that'd work appropriately, and my friends told me to just burn each one to multiple CD's because it would be too hard. Glad it worked out ^^
