It's gone from Freesat from both my Foxsat-HDRs but still available on non-Freesat. If you have a Foxat-HDR, did you leave it in standby? If not, C4 HD will be removed from your box at the next Housekeeper boot.I don't think C4HD has left freesat yet (even though they said it would leave yesterday).
It's still showing in its usual Freesat slot - but the EPG only goes up to the end of today (friday).
So I suspect Sat is when it'll actually go - and we'll find out whether it's staying FTA.
I'm working on an update to Remote Scheduling for Foxsat-HDR that will allow you to schedule recordings for C4 HD non-Freesat through Remote Scheduling Portal.
