I bought a few movies the other day in preparation for my XA2, which should arrive sometime tomorrow. I've only opened one of them, King Kong, and when I checked out the underside, I noticed light scratches on the disk. Will a few light scratches cause problems in playback? I've read that HD DVDs are more prone to skipping and whatnot than regular DVDs if there are imperfections on the disk, so I'm just wondering. I bought the disk brand new from Frys. Is it normal for new HD disks to look like this?
