Scratched DVD at fault?

[curly~sue]

Hello!

I bought a previous;y viewed DVD from our local rental shop a few days ago. As I began to watch it, about 10 minutes through it, it jumped all over the place, then froze. After what seemed like ages it returned to the DVD menu and I removed the DVD. I saw that it was absolutely covered in scratches, really deep ones! I didn't check it when it was bought as I naturally assumed that if they were selling it on, it must have been checked there. Now my DVD player doesn't work at all! I've tried numerous different DVDs in it and all that comes up on the television screen is 'No valid disc'. Can anyone please tell me how to rectify this? Is it just coincedence or did the bad DVD ruin it? Many thanks, curly~sue.

try putting a cleaning disc in it there might but some muck on the lens!
