Just read your first post so I've set my box to record C4 news so I'll see what happens for me.
Hold off any resets until later.
Definitely an issue with your box as it all worked fine for me yesterday.
Try the options 2 & 4 first but it's likely you've some index corruption on the hard drive that only options 3 & 5 will solve.
Thanks so much for going to the trouble of doing that, very kind. I will follow that advice.
