Hi All,
I've got a very high cpu load (about 90%) when I use LiveTV or when I watch
video. I don't think this should be normal.
Here's my setup:
P4-3,0
Hauppauge Pvr500
Nvidia FX5700LE
Gentoo 2.6.14-gentoo-r2
Output of lsmod (only the important ones)
Module Size Used by
nvidia 4084336 0

Installed nvidia stuff:
* media-gfx/nvidia-cg-toolkit
Latest version installed: 1.2.0402.1900
* media-video/nvidia-glx
Latest version installed: 1.0.8174-r1
* media-video/nvidia-kernel
Latest version installed: 1.0.8174-r1
* media-video/nvidia-settings
Latest version installed: 1.0.6629
I installed the nvidia drivers downloaded from the nvidia site and I do see
the nvidia logo at startup of X
I'm using kde for X and my PVR500 seems to work ok.
But I really don't like the quallity of the picture. It's by far not as good
as it is on my normal tv. It's a bit flickering (like the picture can't
catch up with the movements) and not completely sharp).

I'm using a 100HZ Philips TV (PAL-B, as I live in the Netherlands) and make
use of Svideo-out of the nvidia FX5700.
Is there anybody who can help me out here Is their something wrong in my
configuration (it's always something stupid I forgot)? Is their a mythsetup
parameter I have to think off? What CPU load do you have with watching
LiveTV? What kind of quallity can I expect with this kind of settup? Please
let me know if you need some more info.
Regards,
Rick
