Anybody reading this article should also read the discussion in the related forum that follows. It points out that this article, while mostly correct, does have some of its own omissions and half-truths.
For example, if you go to Amazon.uk to look for "Total Recall" as mentioned in the article, the Amazon.uk site lists it as a Region 2, PAL disc. If that's true, it's not going to look right on a player in the US.
Interesting read either way...
