Recording From Digital Channel While Watching Another Recording TV Programs While Watching A Different Channel On My NTL Digital Box?

Recording TV programs while watching a different channel on my NTL digital box? - recording from digital channel while watching another

I have recently updated my NTL box, analog, digital, since I was a TV program while you can not have another channel on the TV to record.
I can record what I see.

It used to be able to watch and record channels 1 to 5 and is in my video or my TV while I was watching another analog channel, my NTL box.

Has anyone a solution, allow me to recored or watch channels 1-5 to be reading a different channel on my digital receiver.
