[mythtv-users] prebuffering pause related to agpgart?

[Darren Richards]

I've had my mythtv setup running solidy for nearly a year now with
FC1.  I decided to upgrade my hard drive and the OS at the same time.
I've installed FC3 with the 2.6.10-1.741_FC3 kernel.  I used apt-get
and Jarod's guide.

With FC1, watching live TV or a recording would take about 30% ov my
cpu.  Now mythfrontend and X together are taking 95-100% of my CPU.
I've searched the archives and I suspect the problem may be related to
agpgart.  I have an nvidia graphics card and I want to use NvAGP, but
even though I set "NvAGP" "1" in xorg.conf, agpgart is still getting
loaded.

/proc/driver/nvidia/agp says:

AGP initialization failed, please check the output
of the 'dmesg' command and/or your system log file
for additional information on this problem.

dmesg contains the following lines:

NVRM: not using NVAGP, AGPGART is loaded!!
NVRM: not using NVAGP, AGPGART is loaded!!

I've tried adding agpgart to /etc/hotplug/blacklist, but it still gets loaded.
I would greatly appreciate any suggestions.  I'm fairly new at this,
so please let me know what other information would be useful.  Here
are my hardware specs:

P3-700 (Dell with Intel 440BX Chipset)
Chaintech Nvidia GeForce4 MX440
PVR350 (not using TV out)
PVR250
SB Live Sound Card

Thanks,
Darren
