Do you receive on your Youview box ITV Granada on each of channel 3 (ITV) channel 33 (ITV +1) and channel 103 (ITV HD) ?
According to this
Emley Moor does transmit ITV HD Granada rather than ITV HD Yorkshire .
There also seems to be a complex Freeview coverage in the Emley Moor region
BT have no control on the channels below 300 - these are all Freeview channels and are from your local transmitter.
You would get the same channels if you purchased your own Freeview box.
You should get Yorkshire on channel 3 - but I think the others will still be Granada as that is what ITV provide.
It sounds as if your box has been tuned to the wrong region, try retuning it again and make sure you select the correct region at the end of the process
And your Freeview box doesn't offer Granada at the top end - around 800+ ?
@V_Meldrew I don't get a choice. I've tried retuning and it just gives me Granada. Just as it did on initial set up.
I live in an area where we can receive TV transmissions from two seperate regions and I presume that this is why, when I retune my box, it asks me to confirm my primary region, I assumed that yours was doing likewise.
Can you get Yorkshire TV if you plug the aerial straight into a TV? if not then maybe your aerial is pointing in the wrong direction?
