As said before the deal completed yesterday that mean discovery today have made some channel changes on Freeview.
Quest 37 > 12
DMAX 42 > 37
Home 12 > 42
I thought discovery might have been a little more cleaver and put Really on 12 and Quest on 17. I know QVC is on 16 but with More4 and Dave on 18 and 19 and both channels have similar content the audience that Quest could pick up would be in that area. And Really being on 12 would catch the Pick and E4 audience. I not sure how TLC does but Discovery could have merge really into it and launch TLC on 12. That way they would have two major tv brand high up the epg.
Interestingly all the Home and Really stuff is still on UKTV Play despite changes to other parts of the UKTV site.
EDIT: Although actually the channel's websites remain active, you just can't click through to them from other UKTV pages now.
UKTV still owns a lot of the content and have a short term deal with discovery. So I expect some shows will be removed but those channels with the content will remain with a change of name.
