[mythtv-users] Stutter with a P3 933Mhz! Gezzz - more STUTTER!

[Steven Christall]

John,

You keep concentrating on your CPU .....  Is the CPU fully pegged when 
you get the stutter?  Does the CPU load then drop if you  pause / 
unpause?  Check vmstat to see if you are paging frantically?  I playback 
on a PCI TNT2, using the latest NVidea driver with a P800 and cpu is 
running 40-50% at 720x5xx.  What exactly is this "old nvidia" card?!  
What is the m/b  Is it VIA chipset?  Have you checked the bios to see if 
both caches on the CPU are enabled (even better reset the bios to 
defaults to troubleshoot)

Best
Steve
