IIRC VIrgin made a hash of implementing how to deal with recordings from closed channels so they had to bodge a solution on, and that solution was effectively make the channels invisible for a few months,.

Don't have this problem on Sky because... Sky went their own separate way, and you can view recordings from closed channels for as long as you like (decryption on the fly I believe, if have an active subscription for that channel).

Indeed a quick search on the blue place and voila, caveat being this is from 2020 so not sure how accurate it is now:

The closure of BBC2 Scotland as part of the launch of BBC Scotland possibly the biggest casualty of this stupidity.
