How do you watch Megavideo unlimited?

Like how do I watch more than 72 mins without waiting again. Its so annoying. I read that you can let the video buffer until it is complete, then unplug your modem and watch the video and when you are done you plug in the modem again and u can buffer other videos. Does that work? I have a windows 7 computer and I have Google Chrome. I dont want firefox so you can forget that options. Any ideas?
