I agree completely with you though. This is a feature that I would be really interested in. I've just built a Windows Media Centre but its not reliable and crashes periodically. It can only record one channel at a time.
I have considered moving to Sky+ but the cost is unjustifiable for me at the moment. There is also the hassle factor to consider as well..
