re. I know people who have Comcast and sometimes when they turn their TV’s on the cable box had switched channels to CNN.

Any chance that's a configuration issue? On my FIOS box I can specify which channel to display on power-up.

“Any chance that’s a configuration issue”

Actually I don’t think so. The cable boxes were not turned off. They just turned on the TV and bam the cable box had switched to CNN, l’ve seen this more than once.
