Especially for newbies, make sure you vote Blu on any of the polls, such as the one at
http://www.youchoose.net/campaign/bluray_vs_hd_dvd
I don't think big studios necessarily look at these, but when these type of polls all show Blu ahead by 68% to 32%, or even better, then it starts getting in the mind set of high-def fans (especially newbies, and purple nurples on the fence)! They get a reality check about HD-DVD not being the way to go, and invest in Blu, to some degree...
Vote Blu!
