Koss DVP2161 Compact DVD with MP3/CD Player
Poor engineering
The idea is a good one, but our experience is that most disks will not play properly on this machine.  The picture fluctuates in brightness, up and down, and in the widescreen view there is a red flare above and below the image which, as described, waxes and wanes.  Not fun at all. We are taking the item back to the seller.  I would not waste time on the suggestions for the ventilation issue discussed in other posts.  Thanks.  Jack
