I was wondering if anyone on this board is aware of a good method of scratch removal or repair of dvds. I've got a few dvds(legally purchased) that I would like to have scratches removed so that I can back them up on blank dics. Should I just purchase some of the devices that I see in the stores like Best Buy? Are some of these devices more effective that others? I don't want to waste my money on a product that doesn't work so that's why I'm posting the question here first. Thanks!!!!!
