I am building an HTPC to connect to a Full HD 37" LCD TV. I am thinking of using MythTV with an appropriate linux distribution (one that includes pre-built binaries of MythTV). The HTPC will have a high def satellite pci card : DVB-S2 and a regular DVB-S card (both linux compatible).

Hardware I am thinking of using for this setup

X2 3800+ 939
2 GB DDR400 Memory
DFI Lanparty Ultra-D
256MB XFX 7600GS

It will be used for encoding/decoding HD content mostly. I will also keep some mp3's in it. Will this setup run smooth with H.264 1080p content doing what I described before. What would you suggest for taking advantage of the H.264 acceleration built into Nvidia GPU under linux (also under windows if I have to) ? I am open to all suggestions. I have been watching regular broadcast since I have bought this TV and it hasn't been a pleasant sight to the eye so far so please help me get this setup up and running.
 
To maximize your nvidia gpu HD results you can use NVIDIA PureVideo HD. I believe its only for windows OS and does your video card support HDCP?
 
I can also get these parts from a friend who is a reseller via trade, perhaps they would be more suitable for HTPC use since linux doesn't take advantage of the purevideo decoder I might as well use o/b graphics.

Biostar TA690G
or
Abit AN-M2

coupled with a X2 4000+ Brisbane AM2
 
The BIOstar board is, clearly, an ATI chipset board.... and you're using Linux which means it's a no-go.

The other one (the Abit) is an NV board which actually has Linux support.

How about the two compared purely from a hardware-only point of view ? I have just read that ATI drivers do not support XvMC which means no offloading parts of MPEG2 decoding to GPU so Nvidia has the upper hand but on the other hand Abit doesn't have HDMI output. Would I lose signal quality if I were to use a DVI-HDMI adapter.
 
I'm guessing you are going with SkyHD satellite service?

HDMI = DVI + Sound. So HDMI without sound is same quality as DVI.

The board I posted about has HDMI but I would prefer to use 5.1 speakers for sound, it wouldn't interfere with sound output on the mobo would it ?

I don't think so, I might just be digital picture only anyways. Seems to me you should not have any problems disableing the sound from the video output and using 5.1 it but I don't know for sure.
