Use any nVidia card capable of full, in-hardware decoding of full
h.264 AVC. I've got two GeForce 210s which I purchased because A) they
were $50/pc two years ago, and B) they did exactly this.
Then enable vdpau. (But that means running the proprietary drivers,
disabling KMS, disabling NOVOU, etc)
Then use any media player with support for vdpau. I know mplayer will
do it. I'm unsure about ffmpeg, flash, etc.
With an (old) $50 card, you can get an old Core 2 desktop system to
serve as an HTPC.
