Hi

I've got some DVD movies that are badly scratched, the DVD drive on my PC fails to read certain parts of it, is there anything I could do to solve this?
Does polishing with toothpaste/car wax help at all?

Thanks.

I doubt toothpaste will do any good. Car wax may, although doubtful. The way that DVDs work is there is a thin metal disk inside the plastic, this disk contains the data which is read by a laser. The laser needs to be able to pass through the plastic to read the disk, but if there is a scratch then the laser will be diffracted and not read the correct part of the disk hence causing a read error. If you are to rectify this, then the scratch needs to be filled with something of the same optical properties as the plastic itself - something that will be nearly impossible to achieve. There are kits you can buy for repairing CDs/DVDs, however their success rate is not very high. If you have important data, then there are specialist companies that can recover the data, but this is expensive.

I took my scratched copy of Win98 to a shop called 'Discs', it was badly scratched and they repaired it for 3.00:)
Though I doubt you have a 'Discs' near you, there should be some sort of computer game shop at your town centre that offer disc repair services.

Often if you try to copy a scratched CD or DVD the software is able to read and re-read damaged sections and often is able to copy OK. Result, a CD or DVD that is able to play normally.
