Seconded.  I'm led to believe a 2.3GHz Core2Duo is the minimum to decode BBC
HD with the current state of code.  My front end is a Core2Duo 2.1 (which is
faster than your P4) and it doesn't quite work (I get pauses).  What I do is
use ffmpeg via a user job to transcode to a lower resolution since my
frontend TV is also only 1366x768.  Doesn't help with live tv though.  I'm
sure as the code gets better the requirements will drop, but I don't think
the P4 2.4 will probably ever cut it.
