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?
