Ahh PCI ata controller, that's the difference. I'm using the mobo controllers. No DMA on the PCI bus would theoretically take double the CPU time (once to handle the ata traffic and again to handle the pci traffic) the way I understand it (albeit not very well :) )
Since you are willing to build a new one, I saw someone mention somewhere that most if not all VIA and Intel mobo chipsets are supported. YMMV. If you get in the 1.8GZ range this problem should disappear from what I've been told. Get one of those new fangled 800mzh intel bus things :) it should work like a dream. Overall, what I've seen about our problem, the bus speed seems to be the limiting factor. CPU isn't the problem. I think my bus is running at 66mzh. Probably anything you can buy now will make a difference I saw a descent barebones on tigerdirect.com for about $200 a while back. I don't see it now but I had to dig a bit before and I'm out of time.

I might give that a try, but I can lock up the box using the keyboard, and I know the key repeat rate isn't that fast. > Mythbackend at 80% hmm.

I think it's so high because the pci ata card I put in is on the same bus as the pvr-350, so they're both compeating for whatever bus there is. I'd say the difference between a 3ghz and 3.2ghz is about 200mhz! ;) I priced out a 1.5ghz, just don't know if I should really spring for something more than that or not...

I had thought this, but I put a fan right over the heatsink on the 350, and it stays completely cool the touch now. I can also "unlock" my system by hitting enter in an SSH connection or ping flood it, and it will come back to live, usually long enough to exit mythfrontend... Thanks though.... If only I could use the box long enough to overheat the card in the first place ;) -Kenneth ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
