It is not just RS. At least some of the main tranmitters are missing CH4, Ch4 HD, CH4+1 and Ch4+1 HD from the freeview epg transmission.
This has happened before with those channels. I think it was a couple of years ago. It populated about 4 days before what was the gap, but with only 3 1/2 days left ...
That is a different issue to the freeeview epg failings impacting the RS epg.
Presumably the RS uses the same process method of displaying the epg as the idential issue is also in this years Web-If epg.
