I don't believe it, I've managed to get dvd to work (all discs).
Here's what I did;
The central spindle that the disc clicks onto I prized off with my fingers. Then I reattached gently to leave a marginal space from the casing.
I think perhaps my daughter had applied too much pressure to the spindle.
Also gently cleaned lens with a cotton bud incase lens was accidently touched with fingers.
Hope this helps those with a similar problem. Sure will save alot of cash.
