hey guys, i just installed my slingbox to my 8300. bad thing is that im only getting the blue screen that says "Communication Terminal" and the SA logo, then I can only get 1-99 "channels" that are all blank. the cable is hooked in and all, just nothing else seems to be working. i can see the "blue screen" on the sling player, but otherwise its not letting me actually use the dvr or even view cable on the tv itself. it wont even show the time when i turn off the box. any help? thanks!
