What is the difference between male-to-male, and regular HDMI cables? It seems like the male-to-male are much cheaper. I'm trying to hook up my PC to my HDTV..should I use this male to male? A 12 footer online is $12-13 on some sites. A regular HDMI one at Best Buy, at 12 ft, would be $75 or more. Is there any difference?
