Exactly the same for me. <br>
I suppose that it's due to the MPEG2 decoding, but reading a DVD with
Xine only takes +/- 50%. Maybe is there some optimizations to be done
regarding MPEG2 decoding...<br>
<br>
On the same cpu-cycle vein, looks like bringing up the OSD takes a
ridiculous amount of CPU (at least 30%, but then I get to 100%) vs. the
fact that no processing takes place.<br>

<pre wrap="">I wonder if somebody might take a stab at helping me understand the CPU
utilization I am experiencing now that I have changed my setup. I have
gone from software encoding to hardware, while I was at it I switched
machines from 1.2GHz Athlon to a PIII 600MHz, since HW encoding would
use less CPU.
Here are the before and after setup, both have frontend and backend
running and watching live tv.
Before:
AMD Athlon 1.2GHz 512MB RAM
GeForce 4
Hauppauge WinTVPCI
MPEG-4 Live TV profile
backend uses 75% or so CPU
frontend uses around %5
After:
Pentium III 600MHz 384MB RAM
GeForce 4 (same as before)
Hauppauge PVR-250
Hardware MPEG2 Live TV profile
backend uses 5%
frontend uses 75%
I am surprised at the frontend cpu utilization on the PIII setup, an
ideas?
