It's not just PSN. I swear, either the 2.2 update is messed up, or my PS3 is possessed by some mischievous imp.
Every time, and this is every single god damned time, I will start a download, then set it to "Download in the background".
What a load of tripe. It never downloads in the background! I even verify that it is downloading by waiting until it reaches 1%, then switch to either playing a game, watching a movie, or running f@h and doing something else entirely unrelated to the PS3.
Then, say, after I've watched a movie (two hours have passed by then) and I return to check my download status, it's at... 1%!
I have to literally press triangle then check the download status, and leave it on the screen for the damn progress bar to even move. Therefore, if I want to download anything, I have to just leave the PS3 on overnight or do something completely un-PS3-related.
Which, needless to say, bites the big one.
