I recently bought a NEC-5320A and put it in a USB2.0 enclosure. I’m using Maxell DVD-R 8X media (made in Japan, I guess code is MXL with some more letters), Liggy’s f/w but can’t burn higher than 4.1X. I tried other 8x media also (I guess the code is: CMC with more letters) and got same results. Ripping is also not fast. I hardly get 3x with DVD Shrink. I’m using DVD Decrypter to burn. Could this be because of USB2.0 enclosure? If so, is there any way to check the speed.
