I have discovery plus premium on my bt account, and Eurosport is in discovery plus premium. Does it effect the hd Eurosport channels on my sky q And also separate from each other discovery plus premium has nothing to do with sky q yes or no

Discovery Plus and Sky Q are separate services. While you may have access to Eurosport through Discovery Plus Premium via your BT account, this does not affect the HD Eurosport channels that you might have on your Sky Q subscription. In essence, accessing Eurosport through Discovery Plus is independent of your Sky Q subscription, so they operate separately. If you have a subscription to the Eurosport channels on Sky Q, that remains unchanged regardless of your Discovery Plus access.
