I loved my very old Sky box, before HD and + came, you could program the Sky box to change channel, once they included the hard drive, you lost that option, the old box could also use magic eyes so you could change channel from another room, however that was all well and good with a 14" TV, but viewing analogue using coax now, and you soon realise with a 32" TV the quality is not there, even with non HD channels.
So as
@Lucid says, you need a cable for every box, there are with some boxes an output, but as said if you daisy chain then second box has limited channels.
So I have a Icecrypt STC3250CCIHD box, it is called a free to air, not freesat, and it does both satellite and terrestrial, and if I want to watch ITV 3 that's great, it will allow it, however to record without a lot of messing around, you need the electronic program guide (EPG) once you find the program you want, you can click on it, and record it on an external drive. And you can even remove the drive and put it on a PC to watch the program. However it is the EPG which presents the problem.
It is spasmodic as to how far forward it will show, and often you need to click on the program for the EPG to show what is on the channel, it works but not very well, and most of the cheap free to air are the same, I have at least three and they show the programs A1, but the EPG leaves a lot to be desired.
We have a 42" TV Toshiba which has both satellite and freeview, but the satellite only receives some channels, had we not got the Icecrypt STC3250CCIHD box as well we may have not realised, as it does get a lot, but all the UKTV programs are missing, I know the dish can get them as the box receives them. But the TV when you scan for channels does not list them.
I am told the HUMAX is good, but was also told the Icecrypt STC3250CCIHD box was good until I came to use it, and to be fair it does receive 100's of channels and the quality is excellent. It is just the EPG which is the problem. As to HD yes it is better, but with 32" TV I need to sit within a couple of meters to see the difference, but use a SCART lead or HDMI and you can easy see the difference.
So I see new freesat for £79 not HD and with HD £179 and hard drive included. But you need new quad LNB and cables into every room, and a box for every room, starts to add up, I am lazy, don't want to route cables, so sticking to Sky Q.
