I was hoping for this for intel solution (less heat and power usage),
but their media boards only comes out with hdmi and no onboard(back
board) optical SPDIF out (you need a casing/enclosure with the optical
module that plugs into the board).

Sounds similar to what nvidia went through.

Trying to avoid transcoding other media files back to mpeg2 for the FF HD card.

Maybe I need to wait for other manufacturers to provide intel (SoC)
hdmi solutions with optical SPDIF out on the backpanel, reason being I
require optical as my receiver/amplifier (NAD T761) is from the older
generation that is not hdmi compliant. Trying to avoid this upgrade
too.

The best board that that I can see so far is this one but requires
external graphics card and is still a desktop (price comparison)

I just need to buy 2x (pci-e to pci) converters for my current 4x pci
dvb-s cards in the pentium 3.

And I would still have some pci-e slots free for future use.

I have this card already: nVidia Geforce 8400GS, Architecture:   G98 A2
and it works great currently with vdr + streamdev as a client +
xineliboutput.vdpau, power usage is still a bit high though.

The goal is to consolidate the two machines to one machine which runs 24/7.

My current power usage for vdr in the home is 330W. I know this by
using a power/electricity monitor device.

Thanks,
