Been using this program for a while and have been happy with it....so far. I've bought some 8.5gb double-layer dvd's and thought I'd experiment with them. It seems that the program doesn't reconize the 8.5s . I've also tried imToo (not impressed) so was wondering if there is any program out there( besides Nero) that will work. BTW I have a NEC 3520A burner with the latest firmware upgrade.
