Query: It quit working after two weeks!

After two weeks of great performance it just stopped working. I put in a disc and the TV screen just displays "READ" forever. I tried it with several discs with the same result. Funny, I bought this unit because of all the great reviews. I guess it's just a crap-shoot with cheap electronics from little-known manufacturers! At least Amazon is willing to give me a refund!
