Unfortunately it was raised during the beta testing but still hasn’t been fixed.
For me I’m seeing the following channels advertised as HD in addition to the normal HD line up:
- TJC (Channel 50)
- Smithsonian (Channel 56)
- Blaze +1 (Channel 80)
- Racing UK (Channel 261)
I also have the Sky Arts HD icon instead of the Sky Arts icon for Channel 11 - although it is correctly listed as a standard definition channel.
