which actually prevents a DVD being played on a Windows PC using Windows Media Player, Windows Media Center Edition or any software players based on DirectShow
they tried that with music cd's.... only to discover, that windows plays it, as long as you booted up with the cd in the drive...
It will in anycase only take about 1 month before the first global decrypter/decoded/de-region/de-css programs include that copy protection......
we have been installing a free de-region program on every machine we sold in the last 4 years.... (not to take copy protection out, but to make it easier to play zoned dvd's)
