What speed do you get through your VPN and what speed do you expect/need (specially for streaming video). Another problem might be that your CPU cannot handle vpn and video at the same time. (so the speed of the vpn is not your problem) If this is your problem, maybe a new graphic card is a solution (which also isn't quiet easy to change in a laptop) guido

What does top say while you're trying to stream video? (if it's hard to copy it quickly enough to paste in, top | cat gives a one- shot display).
