I’m brand new here so I hope someone will be able to help. I’m not very gadget minded so please make any replies very simple – thanks! We’ve had a PVR 9200T for several years now and on the whole it’s been very good. Just recently it has developed an annoying habit of recording a selected programme Ok but with no sound. In the “programmes recorded” section in the Menu the programme has a little box with a green rectangle with a minus sign superimposed. We don’t think we’ve done anything different with these recordings, they just seem to happen. About 3 now have been affected in the past few weeks. Anyone can help please?
