Apex AD-3201 DVD Player
powerful and inexpensive
This machine has features on machines costing much more, and some that they don't even have.  A  zoom function is included which many machines even costing more do not have.  Another nice feature is the remote has a type of volume control, many DVD remotes have absolutely no way to control volume meaning the need for two remotes by the armchair. The remote here controls the audio output from the DVD.  Even though a universal remote would be better this works adequately.   So far I have had no problems with the machine, playing DVD's and CD's flawlessly.  I have no experience with playing MP3's. The inexpensive price is quite a plus too.  Highly recommended
