while trying to play any media file, console return

i'm almost sure what is the reason. I boot windows xp 32bit with /3GB parameter in boot.ini which allowed system to allocate more than 2GB memory. it's needed for some games which eats huge amount of memory. anyway i got this error only when such games is running. i've tried to edit foobar2000.exe and make it able to use more than 2gb memory but it doesn't help. anybody know how to solve this problem?
