Does DVI make a big difference vs component input? Some say its just a sceme by Disney and some others so recording can't be done from DVDs and technically it may be better but most can't tell the difference if put side by side. Is this True? is there a website with photos that compare the 2. Also I when I was buying the TV the sales guy kept pushing me the 110.00 Monster Component Cables, I settled for the 30.00 monster component cables since some say that there is a difference between the real cheap 10.00 ones and the 30.00 ones but nothing much between the 30 to 100.00 ones, is this true?
