I'm using Roku to get Pandora and Browsing and Search are severely limited.  When I select Browse I only get two categories, Top Stations and Top Decade Stations plus My Stations, and when I search it won't even find stations that I can get on my PC, for example a search for "Mardi Gras" won't turn up anything.  Why is this and how do I fix it?  Pandora is pretty useless on my TV via Roku if this can't be fixed.
