[mythtv-users] Pegged CPU on HDTV - misconfigured?

Tue Jul 18 15:12:40 UTC 2006

When viewing HD content, my CPU is pegged and it's a little jittery. I get a
bunch of "NVP: prebuffering pause" outputted to the terminal that started
mythfrontend.

I tried enabling xVmc, but should I use "Standard xVmc" or "VIA xVmc"? I'm
currently using standard.

Some posts said you need to compile xVmc support into MythTV. I used Jarod's
guide, so I installed Myth via yum. Is it enough to set the xVmc setting in
the mythfrontend?

I'm currently using the 8756 nvidia driver, but previous used 8762. 8756 is,
according to the wiki, the currently suggested driver.

Below are the outputs of mythfrontend and mythbackend

System Specs
P4 2 gHz
512 MB RAM
nvidia 5200
Avermedia A180
SATA 300 GB Maxtor HD
On-board sound

I'm sure you're sick of answering these newbie questions, so thank you in
advance. I have done a lot of reading but I just haven't found anything that
seems to help. And yes, I was watching "The View"
