so my brah recently got an hdtv with a built in tuner. he connected it to our digital cable, straight from the wall (ie, not through the cable box), and what we're getting is something strange... it's impossible to tell what channel on the tv corresponds to the actual cable channel number as decoded by the cable box. there seem to be a ton of channels (some even hd), but we can't figure out how to get it to tune in such a way that it corresponds to the cable listings... e.g. we have no way of finding a specific channel like ESPN HD, or whatever. any ideas? we're running comcast digital cable, straight from the outlet to this tv: http://www.amazon.com/Samsung-LNS40...r_1/104-0331628-5103102?ie=UTF8&s=electronics thanks!
