I have this DVD copy of a musical I performed in last year but I eventually have to give it back to the person who recorded it. I'm trying to make a copy but the files won't save to my computer so I can burn a new disk. They're read only which I'm assuming is what the problem is. Is there any way around this? I really want to have a copy of my own performance. They are all .BUP and .IFO files.
