Region Free players are not a part of the DVD standard, however, it should be noted that DVDs are coded for playback in specific regions. If you have favorite movies in, say, Japan, you may not be able to play them on a standard American DVD player. A few DVD players offer a sector zoom which allows you to magnify the picture up to four times. Some players display the active sound channels in LED form on the front panel display. Some players offer remote-control of the brightness of the display, even to the point of turning the display off.
Some players offer two-speaker simulated surround sound.
Okay, we have taken a brief look at the major DVD player features. I scouted DVD players at Best Buy and checked out Video Magazine's last buyer's guide to try to get a feel for the brands and players that are available. I am not going to be able to mention every player by make or model here, nor is this going to be an absolute price guide since prices will vary between stores and using mail order. DVD players basically fall into four tiers of pricing. With minor exceptions, as you add more features, the price goes up.
