My HDRW720 sometimes play DVDs that someone made with display of no color (black and white).

I upgraded to the lastest FIRMWARE when I first bought this floor model. The only thing I did not possibly performed properly is when the display showed no disc and the tray opened, I press the button to close the tray.

Anyone else has this problem?
