I had an error (can't remember what it said though) when trying to Shrink "House of Daggers." I don't know the film studio, but I just did a 8.5GB backup using DVD Decrypter.
Also, once in a while I get a strange message when I tried to burn an ISO onto the DVD+R, and it says the ISO size is too big, do I really want to do that. I did it anyway, and I thought it would be a coaster. But it played fine on the DVD player. That happened with "Hotel Rwanda".
Off topic, I guess, but my gripe right now is the apparent poor quality of the 16X DVD+R from Prodisc (Legacy label). They're cheap, but they can't burn at 16x. I ordered some Verbatims because of a rebate. I'll have to use my spindle up first.
oh well.
