i've downloaded this this japanese animation and it is in subtitle. on my laptop, the sub title goes well with the sound. however, when i take it to my desktop, the sub title is like a second or two off from the sound. what could cause this lag on the desktop? thanks for any response.
laptop: p4, 2.66GHz, 768MBram
desktop: p4, 2.20GHz, 640MBram
thanks.
