I have an old version of usb modchip (do not know which but its the one with the cable and two soldering points). The screen freezes when I swap the disks and press X. Last time I was using it was only the purple disks (CD) I was backing up, while now they are silver (DVD). Does it mean that my modchip does not work with DVD titles? Is there any way around this problem? Appreciate yr feedback.
