Can you clarify your post –
Looking into the series CRID’s which look to be oK.
A epg search for todays It Takes Two finds content on
102 (HD) 108 (SD) 969 (HD) 970 (HD) and 971 (HD).
If I set todays It Takes two from 106 and choose the one off HD option I only get one 1 scheduled recording which is what the codes indicate is the correct outcome.
The situation is more complex id you choose SD due to BBC 2 having SD options for Scotland NOI and Wales.
Can you confirm same outcome by trying the above ?
