DVB-S2 card is a TBS6981 - dual tuner.
DVB-T card was a HVR1100 but with this move, i need to look at a USB
Yes, i can record 2 HD feeds and watch a 3rd (be it from DVB-T or
recorded). Based purely from BE > FE network utilisation, LiveTV 1080i
takes around 5Mbps sustained, so i guess you could consider that a
ball-park figure for required HDD speed. i've seen a max bit rate figure of
12000kbps for a recording though..

i've also done yet more changes since my original post; moved from an ATX
board to ITX board for the BE system. bottom line power draw looks like a
further drop of around 5watts.
the atom 330 FE is also running far better than the hype on here (as a
purely playback device). if you look at some threads here, the atom is a no
go area for anything. there's a few of us using atoms for FE-only and i now
approve of their use :P fwiw, i'm using the Zotac ionitx-f-e board so does
have VDPAU capability.
definately forget the atom (and the amd fusion) for a BE device though. my
E6550 system can load mythtv components around 4 times faster than the atom
can, so i dread to think what sort of results that would have on database
