Synopsis: Enter the details of your problem here

Recently I upgraded my grapchic card from a very old ATi Rage 128
wich lacks Dx9 support to a nVidia FX5200 based card from ASUS.
The rage card worked fine using overlay mode and the main
reason to change the card was to use dx9 and to reduce CPU
load when only displaying the GUI. (used around 40% for me)
and thereby lower temperature and fan noice.

To my surprise the new graphic card did not help much.
GUI still uses about 30-40% CPU, and playing recorded TV
or mpeg 2 files does not work at all from within MP.
CPU usage goes up to 100%.
When playing recorded TV in mediaplayer outside MP CPU
usage is about 95%. Not much left for MP to work with.
With the good old ATi rage playing recorded TV in mediaPlayer
used about 50% CPU.

How can this happen?
How much CPU can I expect MP to use showing the GUI?

I downloaded trial of nVidia codecs with hardware acceleration,
but I can't make either MP or media player to use it.

How can I make the players select nVidia Codec?
Does the nVidia codec make big differance?

The only good thing right now is that watching TV works
faster and better than before. In picture menues does not flicker anymore.

    I wouldnt be surprised it didnt do a lot, the video can will take some of the loading off but a 750mhz cpu isnt really fast enough. MP doesnt use a lot of cpu time though in playback as I tested playing back a 1080i HDTV recording and on a 2600+ and the nvidia codec it used 30% in MP (2% more than WMP).

    At last I got it to work. Had to unregister all other codecs.
    Now playback of mpeg2 files uses about 30%-50% CPU.
    The nVidia codec really made a difference.
    750MHz seems to be enogh if only the hardware is configured to be used.
