Well, my PS2's getting fixed, so I started playing GT2 again, and I decided to go back and get all the license golds. I finally got gold on S-7 (Viper at Laguna Seca), and I thought that was pretty sweet so I better save the replay. I don't know if I've ever even bothered to save a replay before, but when I bring it up it asks "Select Number of Blocks" and it lets me pick anywhere from 3 to 11 blocks. So, what's this do? I just picked 3 blocks and it saved it. Is there a problem with that? Would the replay somehow be higher quality if I saved it using more blocks? I can't find anything about this on the forum. I even did a Google search for "select number of blocks" and it got zero results.
