What's the deal with the M-Lock versions of dvd's? After watching a couple of xfiles episodes at the weekend I forgot how much I love it so went to buy a couple of seasons, only there are 2 versions, the normal version which is around £50-£70 and the M-Lock version which is £12.99. As you can see just a wee bit of difference in price. From the looks of things they still have all the episodes though
