my main computer has a burner insatalled and a usb burnerthat i use without any problems.my laptop has a dvd rom that i play the movie in then burn to the usb burner without any problems.Jus tuse the shrink iso to decrypter explained previous,however I have,nt tried using two usb burners.
i haven't tried using both when this PC had Windows 2000, it wouldn't allow both to be used, but at the moment (i'm using XP now) each USB burner has it's own drive letter and Nero can see both drives. maybe it's alright after all...
i'm just doing some testing on m2 2 enclosures. made the mistake of turning one off during the lead-in process on a burn on other drive and Nero hung for ages, then sprung into life. will have to CRC check that disk afterwards; but it seems you can have more than one USB burner attached at once. yay
