One thing I'm not sure about is do I need a PVR card to do any recording or
can I just use a DVB-T card and MythTV then does the recording from that?
Also do I need to split the antenna cable two ways to go to two cards or can
the cards communicate with each other?

Ahh good - I was hoping to use an LCD monitor and a couple of speakers (or
maybe just the speakers in the monitor but I'm not sure the quality will be

I'm reading through the documents and wiki at the moment. I hadn't caught on
to the client/server architecture. I assume the machines are connected via
ethernet LANs. Arrgghh - more choices :-)

I think I'm just beginning to understand the power of MythTV. Initially I'll
just be going for the single machine. I've found some nice looking
multimedia cases but it's hard to find details such as do they have an IR
port on the case and so on. Also mini ATX looks good but only supports two

Nice to hear that, slower machine = lower power = less noise. Plus a useable
interface with wife - perfect!
IR is one of the areas I've never set up on a PC so I'm not sure what the
correct options are going to be - I need to do more research.

Thanks for that - you've given me more to think about than I thought I needed
to think about - if you see what I mean.
