upgrade a m-1000 mini itx for HD

Hi all

I have a via mini itx m-1000 which has 1gig processor and 1 gig memory this
is housed in morex 2699 case and runs off 60w power supply.

This is excellent for a frontend only to play back dvb-t SD material.
However, I would like to see if there is a cheap upgrade path to get this to
play HD material. There is one PCI expansion slot and ive seen a couple of
PCI 8400gs cards about so I was thinking one of these and use VDPAU to play
the content.

Has anyone tried this? Would HD play ok?

Thanks for your input

My Via Epia was unable to use VDPAU because the CPU lacked the CMOV
instruction. A Nehemiah/Esther CPU is required to get CMOV and thus
VDPAU. One way to check would be to look at the kernel you're running
-- i686 should be good for VDPAU, but i386/i486/i586/Cyrix/Samuel/Ezra
("Eden") is not.

You may not need VDPAU, though, The UniChrome graphics built-in to
your Via board comes in two flavors, one of which is limited to SD,
the other of which can play HD. So if you have the right one, you
should be able to play HD content with somewhat less than 100% CPU. I
don't believe UniChrome + XvMC supports all of the fancy deinterlacers
that VDPAU does, but when outputting to an SD TV, onefield should be
sufficient.

Anyway, I ended up replacing my Via Epia board with a 1.4GHz P3 with
PCI 8400GS, and that combo works great, albeit with higher power
consumption (60W power supply browned out, upgrading to 80W fixed it).

You are assuming mpeg2. It would still choke on h.264 material.

Fortunately this one includes a Nehemiah processor and the CMOV extension
so i'll try a pci 8400gs as a cheap upgrade to HD. The 60W external power
supply should be enough.

the HD source will be BBC & ITV HD from dvb-s source so its h.264 material
not mpeg2 :(

thanks for your advice
