I'm not to bright when it comes to computers. Here's what I want to do. I would like to listen to Pandora Radio, on the internet, and get it on my Home Theater System.Maybee even access my Music Libary through my HT. Can I just run a USB cable ( my pre pro has a connnection for this ) or do I need a unit like " Slim Devices" Squeezbox. If a USB cable is the correct way, I do need 45 ft of it. At this distance I understand I need to buy a USB active extension cable ( x 2) Thanks
