On my latest Comcast bill there was a new channel guide. It said the local hdtv channels (CBS, NBC, etc...) were avail on ch 187-192 and these channels were included with the standard cable pkg "with hdtv equip". Ie, you didn't have to pay for the digital pkg to get the local hdtv channels. I was wondering if a hdtv had an ATSC tuner, would it be able to access these channels (what's the highest channel on the tuner) or would I still have to rent a set top box or cable card from Comcast to access these channels? Just curious, thanks.
