You are absolutely right, the P4 has indeed 2.4GHz (and 512MB of RAM) Which makes it the more surprising that on SD channels I am getting cpu utilization in the region of 80% to 95% It should be a lot less?

Do you mean P3 or have you mistyped the clock speed? The slowest P4 was about 1400MHz, I thought. Surely one wouldn't be underclocked by such a huge factor.

What kind of deinterlacing settings are you using with Xine? Full-rate Greedy2Frame (which I'd recommend) will probably cause a load of 50% to 100% on that CPU, depending on how good your graphics card drivers are.

Run xdpyinfo and make sure XVideo is listed in the extensions (the extensions come fairly near the top of a *lot* of info).
