DON'T BUY THIS MACHINE
I purchased the Philips Model 621 and it would not even recognize the DVD when I inserted it.  The message &quot;Please insert a playable disk&quot; kept appearing.  I took the machine back and bought another one, same model.  On our first movie, WHITE CHRISTMAS, it worked fine for about 1 to 1 and 1/2 hours.  Then it froze.  After a few minutes the same message, &quot;Please insert a playable disk&quot; appeared again.  I don't intend to buy another Philips.  Sony, RCA, and Panasonic are all looking better.
