How do you change the channel??? Ok, seriously, though... I can't BELIEVE I can't figure this out. I just joined the ranks of the cord-cutters and ditched my cable for antenna + Netflix/Hulu/etc. I was already aware of the whole multi-stream DTV thing... but how do I change the channel to, for instance, 44-1? "4, 4" puts me on cable 44. "4, 4, 1" puts me on cable 441. And searching for an answer has been futile! Help!
