Movies pauses

[Ninja82]

Hi. When I am watching a movie on my Mac they pause constantly for a sec and then it continues on but is noticeable and annoying. I thing I had a similar problem on Windows long time ago which was a problem with torrent clients without cache support. Because the Hard Disk I was watching the movie was the one used for downloading the files it was causing those pauses. On the MAC is not like this. I stopped all software that use hard disk and the problem still persists. When I restart the MAC everything comes back to normal. Any ideas why this is happening?

 

My Specs:

MAC OSX 10.6.3

INTEL CORE 2 QUAD Q9550S

MSI P45-NEO3-F

2 x 2GB CORSAIR 800MHz

MSI NVIDIA GTX260 (QE/CI Enabled)

2 X LGW2286L MONITORS

1 X 300GB WD Raptor

1 X 320GB WD

1 X 1TB WD

 

EDIT: 21/05/2010 Well I think I found something... I am using 2 monitors and it seems when I switch off one of them is causing those pauses. I switch on the monitor no pauses. Weird is not it?
