[QUOTE=joelrosado;2086264]Thanks, Wombler. At very careful inspection with a lot of light reflecting, sure enough, there were some fine scratches on the DVD. Thanks for the information.[/QUOTE]
If possible you should exchange the disc but if that’s not an option you could try one of the liquid based repair kits as they work very well on minor scratches.
They use a polymer based fluid that fills the scratch with material that has the same optical properties as the plastic of the disc.
All you do is wipe it on, let it dry, then wipe off the excess so it’s pretty simple, it’s invisible and doesn’t in any way damage the disc.
If it’s a bad pressing though then unfortunately no amount of repair work severe or otherwise will resurrect the disc.
