Query: Quality control is an issue

I purchased my PD77b from Samsclub, but since they have no reviews area, I wanted to provide some useful feedback somewhere. My player did not work properly out of the box, it decided to play DVD's only 1 out of 20 tries. The other 19 times, it gave a "No Disc" or 'Disc Not Avaliable" message. When I called tech support, they had me move the lens mechanism back and forth for 30 seconds. That did not solve the issue, and told me, they have a known issue with their product. Haven't decided if i will try for another one and hope i get a good product or get a different DVD player entirely.
