Are you serious ?

I can decode pretty much any MP3 with an ARM9 running at 48MHz ....

Most video come with a 2 channel PCM, And for DTS, AC3 and others most
would passthrough those via the SPDIF port or HDMI

And for saying that what I wrote isn't true, did you fully read my
message regarding CPU usage...
my C2D is currently running at 1.6GHz (ondemand cpufreq profile, and
it can't go any lower)
playing a bluray RIP, full bitstream h264 1080P video:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
22493 myth      20   0  707m 223m  46m S    7 11.1  26:59.36 mythfrontend.re

7% ....


That's with a DD+ 5.1 channel audio

what processor do you think is required then ?

Most of which aren't supported by mythtv or ffmpeg anyway...
