I have had my Humax pvr free-sat box since it came out and along with my Sony tv have been happy.

I have two aerials attached to my humax

Now I need to change my tv and have ordered one with a free-sat tuner and a free-view tuner. I notice on the humax there is a lnb out between the two aerial in connections, if I connect my new tv to this lnb out connection can I use it independent of what channels I set my humax to.

You will only have a subset of the total channels available while the Foxsat is on or recording (depending on which channel tuner 1 is using). You will more than likely have a quad lnb, if so you really need a third coax from the lnb.

Thanks Graham,
yes I have 4 LNBs and will have to drill the hole through the wall a bit bigger. and use a twin core cable. I was just hoping.
