I was about to come ask why imgburn was insisting on formatting my DVD+RW when I'd never had to do it before....
...well it turns out the program I had been using before (growisofs) does formatting on the fly and never does a complete format. So problem solved
Anyway.. Thanks for a great program for burning (Vista) on Vista! If I continue to use it (ImgBurn or Vista ) I'll be sure to make a donation.
Thanks you sexy guys!
