Forgive this dumb question but I haven't kept up with technology apparently. I've got a coax cable from com cast, goes to their digital converter, then coax from digital converter to samsung ln t2642h. Bought the above pioneer vsx 820 but it does not have a standard coax terminal in the back. I know it can be done but how do I get the cable signal to run thru the receiver so I can get audio thru the speakers? The tv has all types of connections including multiple hdmi and so does the receiver. It is confusing me since previously just ran coax directly to a receiver then to a tv. This in advance.
