If I'm watching a video file on any media player.. or watching a youtube video.. or even playing a video file off a dvd in the drive.. or listening to something on itunes..
every 45 seconds to a minute there's a 1 to 2 second shudder, or stutter while it's playing. Audio, video, either or both together, they both do the same thing.
I've watched the CPU usage spike a bit each time, but for the life of me i can't figure out what's going on.
I have enough resources.. 4 gigs of ram, 3 gig core2 duo processor.. i turned off everything else, but it still happens. What could the puter be doing that it needs that much processing power every 45 seconds?
any comp nerds have any ideas?
