Headless backends need a minimal spec, harddrive throughput and RAM
are probably the most important things. Beefy CPU is only really a
requirement for HD or if you're going to be doing lots of
transcoding. On my P4 2.8Ghz (HT) backend I can transcode at around
40fps, so I can get through several hours of the day's programming
Having video storage and the OS (specifically database) on separate
drives is a good idea.

DVB doesn't require any decoding as it's a digital stream saved
straight to the disk as MPEG2. If you plan to use XvMC (not really
necessary for SD stuff on reasonably spec'd machines) then you'll
need an NVidia card.

I don't know anything about doing this, but Western Dig recently
launched some SATA drives specifically for AV/Media Centre usage, so
I'd presume they're designed to be left idle and running for long
periods of time.

Of you use the over the air guide on Freeview (EIT), you'll get 7
days for most channels. If you use the xmltv grabber with the Radio
Times data, you'll get up to two weeks depending on the channel.

I'd say stick with Myth for the time being, then when you get that
stable, give LinuxMCE a go: "If it ain't broke, fix it until it is"

No; everyone has teething problems to start with, but once you iron
them out you should be OK!
