About Media Go... do you have to install this onto a computer? It messes up Win 7 something furious. If not, how do you USE the thing? It seems far too complicated to use it. I'd really like to know how to use the desktop themes, but I can't seem to get it to even realize that there's anything on the PSP without it. Please help. Is this the same thing as Media Manager? If not what are the differences?
