The initial idea of Television came from two British scientists, Ayrton and Perry. In the 1870s began to be produced first photoelectric cells that convert light into electricity. Ayrton and Perry found that a number of such cells may record variations in the intensity of an image – a series of lenses can focus light on the cell portion of each image, and as more light was achieved with both generate a stronger current. If the cell current can be used to properly light a string of bulbs found in another place, then the image can be reproduced.
Those were hard times for the two inventors but eventually they managed to go all the way with their idea or should I say vision. I don’t know who came up with idea vhs to dvd. It is a good one.

An important thing to know before you make a DVD is to know the PRC of the released DVD. It can have values from 1-8 and refer to geographical regions where current DVD can be restricted to run. For example, DVD players are restricted to operate on a certain region (usually 1 to 2 for America and Japan and Europe). Unlike DVD-ROM zone change allowing a certain number of times, DVD players are locked on one region. If you make a DVD using vhs to dvd you have nothing to worry about. This does not apply here. To get rid of this inconvenience, or modify the movie (DVD) and make it run in all regions FLASH-PROM or reprogram the unit with a DVD-ROM RPC-1 version.
