Hi
Any one suffering the same...........
We have a Humax set top box; until a few weeks ago it was possible, using the EPG, to see all the upcoming programmes on most channels for a full week. Now we are lucky if we see the programmes on any channel for one day!
With the most recent changes to Freeview, I thought that this could be the source of the no-show'!
I did a re-install this morning but the problem is still present.
The Humax box is relatively old, could it be that this piece of kit is passed its sell-by' date.
Any suggestions? My location is BA21 4NW.
Regards
Bruce

I've a feeling this is related to some recent bugs in the EPG due to some changes in some channels on the Local multiplex and as usual Humax and Sony boxes seem to be affected.
Just bear with it, I'll post back if I can get any update.

Bruce: I had a look around and found this:
https://myhumax.org/forum/topic/humax-epgs-not-displaying-properly
The thread seems to be about what you are experiencing, and presents a solution of deleting services that are not required, thus reducing the amount of EPG data that needs to be stored.

Well done and thanks for that, I wonder if Bruce has tried it?
I found something similar but it was years old so I didn't consider it, I didn't see that recent one!
