I have a Slingbox Tuner set up at my parents house so I can watch local sports from where I live. I haven't accessed my Slingbox in a while (as it was the off season) but when I went to access it today, there are only a few channels that come through. Most channels I go to just give me a blank screen and the "static" sound. I originally thought this might have something to do with digital switch, but I read somewhere else that this shouldn't matter. Any help would be great!
