Yeah, I was reading the specs on DViCO's website and they mentioned that 
having a P-III 800Mhz with only a 128MB of RAM would suffice if you happen 
to have a video card with DxVA.  (what's the story with DirectX Video 
acceleration?  Will it never be supported under linux due to closed 
Mickey$oft standards?)

Yeah, we have a microcenter around here.  I can take a look to see what my 
options are.  I may even be able to get my hands on an old AGP ATI Radeon, 
but again, the problem is that the system in question doesn't have an AGP 
port.   But now with Todd's suggestion of having a two tiered 
frontend/backend setup, I maybe able to get something going.  (However, of 
course, it still defeats my original intentions of not wanting to have two 
machines up and running 24x7.  Would like to conserve as much power as I

I sure does.  Thanks.
