Sounds like it - btw, just a heads up, but I find DL-RE discs take a huge amount of time to burn - IMGBurn has an option whereby it re-writes the data automatically as it's burning if it doesn't burn it correctly the first time - make sense?
I think my record was something like 4+ hours, perhaps longer at 0.8x speed. In comparisson, a DL-R took about an hour, but obviously cost more $$$.
