Hello, this is a reply to another post here that the forum wouldnt let me reply properly to. I also have a memorex dvd+r/rw 2.4x8AA and I have been able to get it working on my old computer however I was never able to copy a dvd using the Nero software that came with it. I was forced to make image files (.iso) of the dvd's first. But I am trying to make it work on a older machine now and I am having problems. I plug it in and the lights come on, my computer recognizes it and installs the drivers and my burning software sees it as well. But I cant get it to open. Its driving me crazy, pleast help if you know anything about this particular problem. I've tried opening it through software on my machine, got a new usb2 card, cant seem to figure it out. Thanks.
