[mythtv-users] Ivtv DMA errors

Cool, I'm thinking about the Albatron KM18G because it got some pretty
good reviews, and it has a built in video-out which might work better
for playing videos and also viewing startup info so I don't have to keep
lugging the monitor in from the other room.  I've got three inputs on my
TV so I'd probably hook one up to the mobo v-out and one to the PVR-350.
Also there are a couple different kinds of microATX board layouts, and
my case has the side-to-side audio jacks, where most seem to be stacked
so that limits it a bit.  A bit pricy @ ~$80-90 bucks, though, but it
might be worth it if it's solid.

Er, "Go get", not "Got get"... (Need... more... sleep...)

I'm rather partial to nForce2 boards, though they ain't cheap
(relatively speaking -- my Tyan MP boards cost way more =). I love my
Chaintech 7NIF2, no problems to speak of, and its not a VIA chipset! 
Though I never had any issues with my old KM266 board (MSI KM2M
Combo-L) with dual ivtv tuner cards either, and my current secondary
system is rock-solid (MSI KM4M-L, one very sparsely used M179). I think
I paid about $100 for the 7NIF2, and about $60 for the KM4M (both from
local shops). The nForce2 board does have the distinct advantage of NOT
using a VIA chipset, so you can be pretty certain it won't have those
DMA issues (both my VIA boards are fine, but YMMV). On the cheap and
non-VIA, I've had good success with ECS K7S5A boards, which use a SiS
chipset and retail for like $30 now.
