<div><br>my opinion:<br>No way is that fast enough. Try a 3400+ dual core athlon64 or the like to do it with deinterlacing and never dropping frames.</div></div></blockquote>

</div><div>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.</div>
