Options

A DVD player does convert a Video standard and therefore the problems will be that a PAL DVD will not play on a NTSC DVD player. However, a multi system TV, that is able to receive all types of signals, will allow you to watch DVD of any standard you want to see. You can also use an external converter to convert the signals from PAL to NTSC or vice versa, but obviously, the best choice would be the region free DVD player with a built in video standards converter.

Region free DVD player – a modern requirement

The days of visiting an outdoor movie theater to watch the movies of your choice is now practically over. You can watch them in the cool comfort of your home, at a time convenient to you. You may like to watch the video in parts, depending on the availability of your time, or you may like to have a family get together to view them. The prices of both players and discs are on the down slide while quality is going up with the application of the sate-of-art technology. In every respect, DVD is the best home entertainment today. But with its phenomenal success has brought in the difficulties relating to region coding or region lock.
