u may have fried the battery

i have a question about my psp. i just reformated my 2gb memory card and then updated it, but now it wont let me play any .avi files that it used to let me. all i really got the thing for was watching anime shows on it. anyone else having this problem now also? and if so can you help me with it?

I think most batteries do that. Probably something to do with a tiny bit of moisture building up on them or something stupid like that.

Yeah, I've had my psp battery run out just from sitting with no use. That's normal I think. Speaking of the psp battery.... anyone notice that if you turn off the wifi network your psp will last like a few hours longer?

PSP ohah i got one but i rather get a ps2

yeah just as long as you stick it back on the charger when you done you have no problem.
