I currently have Comcast cable but I would like to switch to Voom due to the low HD channel count with the Cable. My question is that when you are flipping through the channels can you see the local channels without hitting any combination of buttons to turn off he dish. Example say local channel is 4 can you flip from 4 to a voom channel by hitting the channel up button or do you have to click another button to switch te dish off or bypass it?
