Input:
This was my first DVD player, and it worked great, had great sound, easy setup, the Noise Reduction really cleaned up the image...(now you wonder why I am talking in the past sense)...but it stopped working after only two weeks and playing five movies.  Whenever I inserted a disc it shut down or told me the disc was dirty.  I'll be taking it back to the shop tomorrow, very disappointed with my first Sony DVD experience.
