So, I setup my slingbox yesterday. Everything was working OK, the remote was fine. When I start watching, the defaul channel comes in great. However, when I change the channel on the slingbox, it goes blank. Every other channel I change to goes blank. Also, when I tried watching the TV, I had the same exact issue. The default channel worked, but no other channels did. Anyone have any ideas about this? Any help is much appreciated!!!
