hey guys i have a question. i have 4 downloads right now, 1 50% doen and 3 pending. will they stop if i play a PS2 game? or do they keep on downloading?

Same situation with the 360, I believe. Sometimes background downloads pause and sometimes they don't. It depends on what's being run. I don't know if the PS2 functions pause downloads. There's only one way to find out!
