Hello @purpleadge , sorry to hear about your problem, I'd like to try and help if i can.
We are working on an issue that affects some recordings and expect to see a fix for that rolling out in a couple of weeks. In the meantime as @Keyinferno a retune may help here. Due to the high pressure the UK has at the moment your aerial could be picking up TV transmitters further away than normal, if thats the case then the signal might not be strong enough to record successfully and a retune will help that. If you see a choice of TV regions suggested on the retune pick the one thats your local "area" and you might want to recreate the series enabled recording schedule once thats sorted.
if you need any help drop me a PM and we'll take a look for you.
