[mythtv-users] Live TV Pauses

[Stephen Tait]

On hardware like that, load average and CPU usage is waaaaaaaaay too high. 
I'm on a 2400 with an nVidia FX MX4000, load average is never above about 
0.3 and CPU usage is at about 1% when watching paused live TV, and hits 
about 20% with deinterlacing.

Number one culprit I'd say is DMA on the hard drive. Delve into hdparm and 
check that DMA is i) enabled and b) working.

I use a VIA KM400 chipset and 512MB of PC2700 with a PVR-250. Other than 
regular core dumps and kernel panics with the latest gentoo-sources, 
everything has worked simmingly.
