Well, I'd say it was a good first attempt on their part. They've got a lot of guts putting an article together like that actually, and it's quite worthy of credit! I think their conclusions for each tested disc were a little weak, possibly they were trying to cater too much to noobies, which isn't a bad thing neccissarily, but I feel that many things that could, and possibly should have been said, were left out.
I have to say, this is the very first time I've ever seen something from CDFreaks that had to do with testing DVDs, that I thought the methods were well formed and thought out. I hope that this sort of effort is something we can expect to become the norm, not just with CDFreaks, but with all review sites
