On a computer screen up close, I can see a difference very easily. 10ft+ back from a 46" TV? Can't really see enough of a difference that I give a shit, and it's worked fine in keeping my 2TB hard drive from getting full, and keeping my 1TB data cap in check.
You must have terrible eye sight.
Granted I don't have a bandwidth cap but I can't see how downloading some 1.5GB HD tv episodes is going to use 1tb
