HD tuners are they OTA ATSC? Cable and OTA are very different.
There are far more channels available on cable than OTA, to access all the cable channels the TV has to have a built in cable tuner. How the channels end up numbered is up to the engineers that made the box. John
I have Charter cable service in Michigan.
I have a Sharp LC-26sh12u TV and a Philips DVDR3575H/37 connected, in different rooms.
Both units have built in HDTV tuners. They are connected directly to the cable, no cable box.
HD Cable channels do not translate the same for each unit.
An example: Cable provides a digital music channel 903. On the sharp, this translates to channel 103.27, for the Philips, the channel is 103.41
Why would this happen?
