I too am seeing the Eurosport 3>9HD channels in positions 537-543 - my educated guess would be that these are included on all packages that have the existing Eurosport 1HD & 2HD - so the "Entertainment & Sports Lite" personal pick & Maxit/XL/Full-House and some legacy "Fun" ones IIRC
I'm on Maxit TV, so get the BT Sport UHD & VM-UHD channels, I also have the Eurosport UHD (Ch523) greyed out. Not that I have a UHD TV.
Also remember the Sky UHD add-on isn't for a linear broadcast channel, it's for VoD programmes.
I'm a Very Insightful Person, I'm here to share knowledge, I don't work for Virgin Media. Learn more
