Another techy question for you lot.

As per my previous thread about looking into Sky HD I've now ordered it, the problem is that my tv only has 2 HDMI sockets both of which are being used by the Xbox and Pc, the Sky HD box and my DVD player could do with also being connected to the tv if this is possible ?

I've seen several on ebay, read a little on the AV forum but no doubt someone on here has got a box that I would need so just looking for some advice on what to buy as they range from £15 to hundreds.

Thanks again !
