Which box offers twin tuner (record one and watch other) like Sky+ HD Box



Anyone knows what are the boxes which offer twin tuners like Sky HD+ box.

I want to record one channel and watch the second channels at the same time.

Also will that box also offer long term EPG and planned recording i.e. if I want to set recording for programmes comming after 4-5 days.

What I mean is exactly the same functions as Sky HD+ (but running on C/N line)


Many Thanks
