I have a Humax recorder, on which I record most of my viewing in order to fast forward the adverts or catch up if I have dozed off
!
I find that any channel shown on the on-screen programme can say 'no programme information' from time to time. I find the way to get it to show the items is to tune in to view the channel for a few minutes, after which it has usually loaded the information. I just tried it on 101 and it worked. I am not bothered about HD and have to say I always choose the SD option.
Hope this makes sense and works for you, good luck!
