they still haven't bothered sorting out out
Well, maybe your inability to express yourself in proper written English has something to do with your lack of influence in these matters.
Seriously though:
why would they? It isn't that much of a problem (just find the next programme in the series in the EPG, and set that), maybe the underpinnings of the software make it difficult to do (it would be an exception case if the design principle is to prevent potentially impossible operations being available for a current programme), and the effort (cost) of providing it is not going to win any more revenue.
Having an independent users' forum isn't about pointlessly complaining into a void, it's about collaborating on getting the best out of what you've got. We've told you what the work-around is. If the unit performs according to its specification (ie what all the information available says it will do that was available to you prior to sale), you have NO COMEBACK - no matter how annoyed you might personally be about any particular aspect that does not suit you (in my opinion, you appear so cross about every little inconvenience that life in general must be driving you towards a heart attack).
My point is: if you don't like what your unit does, find another which performs to your liking. I guarantee that you won't... or at least if you can it will be a lot more expensive (eg a mini-PC with a DVB-T2 tuner and software you can tweak to your heart's content).
I had been pretty much ignoring your diatribe, but this time I contributed a suggestion to get you over your problem. I don't think I'll bother again. The below goes for me, too (or maybe the irony is too subtle):
"Give me the courage to change what can be changed, the serenity to accept what can't, and the wisdom to know the difference."
