".....watch on TV thru a DVD player which I do not believe checks for the region in which it was burned for ...."
Stand along DVD players also check the region code. For some stand along Players/recorders you can obtained "Hacked" firmware that makes the Player region free. This is what I did to two Liteon DVD players/recorders. I was not so interested in the "Make region free" as I was to add the 3 Hour record time. For Data/Home Movies, most software does not add the region code. Region code is normally restriced to "store bought" DVDs.
Generally the "Region" can be changed 5 times. On the fifth change, you live with that region, unless you can (1) for a computer DVD drive find a program to reset the Region changes back to 0. or (2) for Stand-along units find a hacked Firmware update.
Thanks a lot!:) I just was not sure about most of the items you listed. Great info.
