Hello, We are trying to decide between Sharp 52" and Samsung 55" (on a good sale right now at Best Buy). From what I've read, since we already have a Netflix subscription, all we would have to do is download the Netflix app, which I am thinking is free. Anyone know if this is available with this particular model? Also on another subject, we have Direct TV now, but only standard dish and receiver. Will we need to get a different dish installed? We know we will need a different receiver... thanks for your help!
