[mythtv-users] HD-3000 artifacts if computer does 'anything' else

I have a 2000+ running as a backend with a 500/350 and a HD-3000 all in 
the same system. I already figure out that you can't actually have it 
with the frontend because if any audio card is in there with it it goes 
from lock/unlock constanty making everything unwatchable. But I'd think 
you could atleast record from the HD-3000 and say the 500 at the same 
time without having to deal with artifacts throughout the broadcast. Or 
just using a frontend and having the network adapter doing anything 
causes the same thing. It doesn't seem to matter, just 'anything' 
happening from another device causes it to make artifacts... Some more 
than others but always 'some'.

Is there a way to actually use the seemingly unbuffered hd-3000 cards or 
do you just have to plan a huge event every time your going to use it by 
making sure you don't do 'anything' else on it while its in use?

No combination of interrupts seem to resolve it. I tried 3 other 
moterboards with 3 different VIA chipsets on them... But those last only 
a couple of mins with the 500 before VIA handles something incorrectly 
and the system hard resets.
