Currently I need to use a Core 2 Quad (Q6600 @ 2.40GHz) to get decent and stutter-free H264 decoding using software (FFMpeg SVN, Xine-lib 1.2, Xine-UI and vdr-xine plugin). With my Core 2 Duo (E7300 @ 2.53Ghz) I didn't had enough juice (stuttering, framedrops, etc).
You absolutely do not need a quad-core CPU and your Core 2 Duo should easily handle h264 decoding. I'd say something was misconfigured or so.
Btw, I use CoreAVC here and the cpu usage doesn't go above about 87% on that x2 4400. The h264 implimentation in ffmpeg was very unstable when I tried it although I heard it's gotten much better.
It's still good news to know that open-source software allowing current fanless integrated motherboards to decode HDTV at ~10% CPU is on its way...
Going from 87% of 2 cores, to ~10% of an entry level CPU is good, specially when the load is taken care of by existing chips. I'd like to have full-HDTV on a single x86 mini-ITX board. I'm now seeing this will happen soon enough, and I'll wait until then before I spend money on new hardware.
