Input:
After many terrible experiences with a computer DVD (stalls, freezes, etc.) the responsiveness of this machine was both a relief and a revelation.  The Panasonic is everything I wanted and although I am sure there are bigger and more complex devices on the market, for normal at-home viewing without hassles or headaches, this more than meets the bill.  I gave it only four stars because I have no real basis of comparison but for me it is a five star winner.  I am delighted with it and commend it to anyone who wants a dependable DVD player at a bargain price.
