It won't be due to their lukewarm attitude to XBMC, XBMC relies on another project for the the VA/dvrs, the name/s escapes me right now. You're probably thinking of ffmpeg. The newer Nvidia "feature set C" cards (including the G210, GT220, etc) apparently support some further VDPAU capabilities tha...

Lowest power CPU for Socket 939?

I have an old Socket 939 motherboard that I could potentially use for a low-budget HTPC build (I pretty much blew all my disposable cash on upgrading my TV, as a necessary precursor to building this machine). Currently it has an Athlon 64 3200+ and an Nvidia 8400GS video card, and with that combinat...

The 5050e may be better from a certain perspective, but it seems to be dead as a doornail (as mentioned above). I can no longer locate any vendors that stock it or any similar parts. So, unless anyone knows differently, if you want a dual core at such a low power level, you'll need to resort to this...

This seems like the best solution so far for a front-end HTPC (or will be once they get the USB issue ironed out). For those running Linux, XBMC with VDPAU video acceleration will take full advantage of the Nvidia hardware.

As I understand it, one reason Ogg Vorbis is less supported is simply because it requires more horsepower to decode: .OGG uses floating-point arithmetic whereas .MP3 is integer-only. Now, this is becoming less and less of an issue as technology advances, but at this point Ogg Vorbis has less tractio...

What Nvidia's chipset has, that nothing else has currently, is hardware-accelerated HD video decoding under Linux (VDPAU).

Generally speaking, trying to "undervolt" an induction (AC) motor is at best a waste of effort, and at worst a good way to wreck the motor.
