Hi all. I solved this annoying issue re: my 16x burner USB 2.0 doing no more than 1.7x burns.
I brought it to work and installed nero on two computers and each computer did the same as home, burning at 1.7x. Then I took out the dvd drive and installed it via IDE in one of the towers and tried nero again, and what do you know but the burner was going full speed just as it should!
My problem is the usb 2.0 external enclosure. Either the enclosure isn't 2.0 (though it is advertised on every internet site as being 2.0.... this is far fetched to be the case I think) or the enclosure hardware is simply malfunctioning. Regardless, atleast I know now that the burner itself is AOK and the problem is in the enclosure, now I need to try to get the people to send me a new enclosure...
glad to know its not the drive, but still sucks I cant use it until i get a new enclosure and i'll be damed after paying for this one if i have to pay for another!!
