Rumbling sound with Hulu Desktop
I have a pretty new MacBook (it's about a year old). I recently downloaded Hulu Desktop (Hulu's application for watching online TV and movies) and whenever it's been playing for a few minutes the computer starts to make this disturbing rumbling sound. The only way I can get it to stop is if I put the computer to sleep and then wake it up again, but then the sound starts again after a few minutes of Hulu. Any ideas?
MacBook, Mac OS X (10.5.7)
