On a couple of occasions this year when attempting to record a TV programme on my DVD/VCR no programme is recorded. All I get is a black screen with the name of the TV channel at the bottom & the words 'No Signal'. To overcome this I have to do a factory reset & re-tune the DVD/VCR then all is OK. There seems to be no particular reason for this, e.g. I set player to record a programme at 22.30 hrs on Sunday & another at 6am on Monday. The Sunday prog recoreded OK but not Monday's. Is this problem caused by Digital TV and/or Freeview as I've only noticed this problem in recent years.
