This seems rather strange, but no doubt someone will tell me why it happened.
Yesterday I watched Songs of Praise on IPlayer not long after the original transmission. The program ran smoothly with only a little buffering in the last minutes. However in the earlier parts of the program " no or bad signal" appeared but there weren't any breaks in transmission. How that could happen loses me, as IPlayer recordings do not come via the dish, but my internet connection. I was watching in SD, download spped ~6500+, via HomePlugs
