Threw in a couple of DVD's I've never watched on the PS2, and they both choked at the layer switch. In fact one, X-Men, went so far as to pop up "Unable to Read Disk" after a while. If it DOES play, it stutters, audio drops out, goes out of sync etc... So, I turned the unit off for a few hours. Decide to throw in the one disk I know for sure where the layer switch is, to give it a test. Fellowship of the Ring: EE, disk 2. I've had this a few times lately, but this disk worked just fine one week before Christmas. I know I at least watched it then. I put the DVD in, it flashes up "Reading Disk" for about a second, and then it goes away. No disk appears. Nor does the dreaded DRE appear. I can't do anything to make the disk show up. Threw in wifes "Sleeping Beauty", same thing. Strangely, I throw in disk 1 of Fellowship and it picks it up just fine. Any ideas? I'm at a complete loss. I'm worried that it's starting to choke on dual layer DVD's... Not knowing the differences in structure etc... This has me somewhat concerned for Gran Turismo 4. I was wondering whether to bust out a lens cleaner disk, but I've heard they can scratch the lens, so I'd like it if someone could confirm or deny that if possible. Hope someone can help, as with GT4 on the way, this is more than a little worrying, especially as I've only had the thing a few months.
