I'm setting up a SB350 today. I'm watching (FF35 on a Win7 PC) BBCA on TWC./Cisco4642, composite video (because component isn't working - need to find another set of cables to see if they're bad).
My use will be almost entirely local - I didn't realize internet would be required for that. I have very slow DSL with frequent outages that would appear to limit the usefulness of the SB.
While I don't understand the need for internet at all (beyond initial setup), what I really don't understand is that Netgear Genie is showing constant 2-3mbps download and less than 100kbps upload. If my video stream is not being uploaded, what exactly is being downloaded?
