Is there any way I can get free channels via satellite and have the kind of hard
You can buy PVRs that work with the free-to-air satellite channels, however they do not have a program guide.
When Windows Vista Ultimate Edition works with dual DVB-S tuners and provide a full electronic program guide.
Which PVR's work with free-to-air satellite channels?
Are you talking about FreeSat or some other way of picking up free to air channels?
I'm very new to satellite broadcasting so have not much idea of what I'd need to set up a system or, indeed, of the terminology used.
What has Windows to do with it? Are you saying that I could get a program guide on my PC?
For DVB-S PVRs, see:
These can be used with Freesat, and requires a dish with a quad-output LNB, as a connection is required from each tuner in the satellite receiver to an LNB output.
Windows XP Media Center Edition (and now Windows Vista Ultimate Edition) contains PVR software and an EPG:
