Hi Jackson.

Thanks for the answer.
The first thing I realized when I learned how to use search on the 
mailing list was that this question is very common so I was already 
preparing to shot myself expecting the hear the advice to learn to use 
search. :) It's a shame.
Ok, back to the point...

The problem here is that I have a little unconventional hardware: it is 
a small form factor Intel D945GCLF2D mini-ITX Motherboard + 
integrated Intel Atom 330 2core 1.6Ghz. I have doubts about it's ability 
to encode 4 channels of D1, besides Intel advertises Atom's performance 
as video encoder: 
http://www.intel.com/design/intarch/applnots/DSS_Appnote_r5.pdf.
I really don't want to setup another device specifically for DVR, 
especially with large form factor. Installing cheap capture device w/o 
h/w compression sounds like a great option, but I'd really like to be 
sure that Atom 330 is capable enough for this. Is there any expertise on 
this?

Regards,
F S
