I'm totally confused here (what else is new) about playing PAL DVD's. Scenario 1. A PAL DVD is region free. Does this mean it will play on NTSC systems? 2. What are the cheapest US NTSC DVD players that will allow you to play PAL DVD's on regular US TV's or do you still need a dual system TV to be able to see these PAL DVDs? 3. Assuming that the DVD player can convert the PAL DVD's for watching on a US TV, can you digitally copy these PAL DVD's to NTSC DVD's or do you need an expensive machine to do so?
