I compiled some home movies on an authoring programme yesterday and the total size was 5.9 Gig. Although this programme has it's own burning facility, it can't compress files. So without thinking I just loaded it in to Clone DVD via the "write existing data" section.
After about half way through burning, I thought, hang on, this is just a "load and go application", I bet it fails as it's too big for a 4.7 Gig disc.
Well, it worked! Wow, I had no idea that Clone DVD compressed files to fit in this part of the programme?
Did the authoring programme miss read the size, or is this how Clone DVD works?
