Watching Freeview and Analogue on the XPS One

Just received my XPS One 20 and all set up.  Very happy so far and definitely makes a worthy TV and PC replacement for the bedroom.  Haven't run it through its paces yet so not getting ahead of myself.

I am in the UK and am using the XPS One in the bedroom as an all in one but largely as a TV.  I have tuned XPS One using DVB-T to watch Freeview, though in my main room I have SKY TV via a set top box.  The Sky TV signal is distributed around the house via an analogue signal.  Being equipped with a hybrid tuner, I assumed I would be able to switch between DVB-T and analogue channels without having to reset the TV tuner.

If anyone knows how I can do this please let me know, if it is not possible with the card in the XPS One, please advise one that will allow it.  I read somewhere the Vista Media Centre TV Pack can accommodate this, not sure how so please HELP!!!

Thanks in anticipation.
