not sure what kind of math they teach down under, but 50gb is not 3x the size of 30gb????? Both are the DL capacity. Single layer is 25gb vs 15gb, still not 3x. it's not even twice as big.
and BR has also been cracked. there's a version of AnyHD that works on Blu-Ray discs as wel, that's why there are Blu-Ray rips all over newsgroups and torrent sites (not that I condone that sort of thing, I don't, I'm just letting you know that the point you made is incorrect.
im talking maximum capacity here.... 250GB for BR and 100 for HD DVD.
for what its worth i am quite good at maths, please research the topic correctly.
ok so there is a crack for BR, i spose then they are equal in that sense of things.
