I'm working on a video series where I review and anaylse television shows. I'm mostly looking at region 1 and 2 DVDs. I need to be able to switch back and forth between regions frequently, which obviously isn't an option with the 5 chances I'm allowed. I read that a good solution would be to buy a second USB DVD drive and simply reserve one for watching US DVDs and the other for UK DVDs. Can anyone tell me if this would be effective? I guess what I'm really asking is, does the computer read the DVDs or does the USB drive? Many thanks.
