When watching videos on my dad's computer online, the video gets choppy (like a game with really low fps) but only happens when fullscreened. On a normal minimized screen (like Youtube's) the video runs just fine.
Here's why I'm stuck:
Internet: 6 mbps, split through a router to 4 computers and we play videos just fine on the other three computers.
The internet's fine since we can all play just fine. I'm also quite sure the computer's fine too since I've managed to pair up the old card with a 22 in. widescreen and a 17" CRT while playing a DVD on the 22 in". We have no firewalls, nothing networking related except for the router and modem. And we use Mozilla Firefox 2. Any other ideas to fix this "issue"?
Note that this issue applies to every online streaming sites.
