I've had a few that skip and jump, thought they were the discs, then got a dedicated player and no problemo.
Plays games fine and I know it ain't the discs.
Just sometimes the DVD doesn't want to work that well.
On some of the older machines there's a slight problem with the DVD laser, and if your disc is slightly warped (as can happen - though it may not show visibly) then the laser can't read properly as it moves to the outside of the disc and the warp of the disc gets worse.
If it works lying flat, leave it like that. If it's already flat and isn't working, phone Sony on 08705 99 88 77 and they'll have a new machine to you in 48 hours. Have your old machine ready to go back with the courier.
