The entire drive assembly in the PS2 is absolute trash, its not just the lens. The entire system is absolutely horribly made. Your system will die, its not a matter of if, it just might last longer than another friend’s PS2. “Cleaning the lens” means absolutely nothing, and lens cleaning kits are snake oil and will do nothing.
The only fix you can do is to raise the laser seat height on your PS2. You’ll need to the void the PS2’s warranty, and have a very small phillipshead screwdriver laying around, but outside of that, its an easy process. This tutorial will give you instructions on how to raise the height of your laser, but is NSFW because its on a warez site.

Your laser will eventually die completely, and be unable to read discs even at its new height, but this solution will work for awhile. And to be honest i would not buy a PS3 in the hopes it’s drive will be better, if only because of how horribly the PS2 is manufactured, i wouldn’t expect them to have suddenly become qualty control masters.
Wilf, there is no DVD format that the PS2 can’t read. DVD is a strict format, they’re all made the same. Sometimes there are different copy protection schemes, like Macrovision or Infinifilm, but these won’t prevent the DVD from being played in your PS2, because these protection schemes only apply when played in a non-standard DVD player, like a DVD drive.
Hades, the PS3 is only “half the price” of a bluray player because the only bluray player on the market is aimed at high end consumers…it wouldn’t take much to make a cheap version of a bluray player. The technology involved does not drive the price up, the fact that the current player is being aimed at rich consumers drives the price up.
