Page 1 of Playstation 2 Scratching Your Discs?

I have noticed that my playstation 2 is seroiusly damaging my Games and DVD`s, Im not the only one a friend of mine rang Sony and sent away his disc and they admited his was scratched was due to the hardware. I bought 007 Agent Under Fire 2 days ago and it is really badly scored around in a circle like the lens of the laser was rubbing on the disc, there is also a clicking sound and then the game freezes.

Has any 1 else experienced this?

By the way it happens worst when the PS2 is in the upright position
(I always keep mine down flat)

I`ve also seen this on my copy of Teken. However, it happened after a party and I suspect it was down to the PS2 getting kicked over at some point while the disc was still spinning. I`d be interested to hear if this can really happen in normal operation.

my cousin had his shrek dvd ruined by his ps2, and had to send the ps2 back cos another disk go stuck in it.
