Satch:I guess I am more questioning if there would every be 16 shows on Sky at the same worth recording. For me 16 in a month would be a great stretch.
You are looking at it the wrong way. The better way to look at it would be to say when do you ever need more than 4 channels recorded? It actually happens once every 2-3 weeks for me. Usually around 6-8 at night when the overlap between something finishing at 7pm and starting at 7pm clashes. I could see a very good use of being able to record 6 channels and if 16 is the next iteration then I would class that as a pretty usable feature.
