[mythtv-users] SOLVED System Load/Performance Question

Hi Bob-

Did you come to any  resolution with this?  I've got an nforce2 system as
well (chaintech) , and I cannot adjust pci latency for IDE either...  I see
a systematic stuttering (1 every 1.5 seconds or so?) of CNN tickertape with
my XP2900, FX5200 system, that I can't help think it has something to do
with PCI latency.  I get occasional glitches in HDTV recordings as well, for
example if someone accesses mythweb while the recording is happening.  I
think this is all related, but like you, I'm not finding any answers by
google.  Thanks for any insight,

Mike
