I'm using 2 or 3 screens so on my 2G laptop I'll open them up and place them off screen also. I think this helps the CPU because the graphics don't have to render the video, but I'm not too sure.
But it's nice not to have to see the video anyway. It now just a basic robotic movement and you click the button every 20 sec. when it turns green. Check forums, email, etc. the new BB 3W will be next, I'm sure it will take 2 months to break it in. Then the Nike Covert later on, maybe just for, like,a trophy.
Videos may discontinue a short while, try your 2nd browser. I may clean the cache or cookies and/or wait till the evening and they resume. Sometimes the videos are less frequent when you're at about 90 creds off a purchase price of your next buy. Understandably.
