(urgent) info. I do check my inbox several times a day, lists more like

I use the gentoo distribution, and everything is straight from portage.
xen-sources and xen are the current ~amd64 (thats gentoo unstable for
kernel = 2.6.20 and xen 3.1.2

Motherboard is a gigabyte board, ill have to look up the exact type later, i
am not at home right now. 
CPU's are AMD Athlon(tm) 64 X2 Dual Core Processor 4000+ (3200+ for file

Capturecards are all WinTV cards. All anolog input. I am experimenting with
a TV over IP provider here in the Netherlands, but nut much luck yet!
