</div>We'll, we're way past 2.6.0-test3 so I'd say these patches are already<br>
in current kernels, though I haven't verified that.<br>
<br>
The bt878 doesn't do hardware mpeg encoding or decoding so you'll<br>
definitely need some CPU horsepower to record with these boards.<br>

</div>bttv is probably already available for your Linux distro. I don't use<br>
LinuxMCE but since bttv usage is *very* common its very likely to<br>
already be available as a loadable module.<br>
<br>
If the module is not already loaded (try "lsmod | grep bttv") after boot<br>
them you may need to configure it to load via /etc/modprobe.conf.<br>

</div>Good for you! That's actually one of the reasons I do Linux. I always<br>
want to know WHY something works, not just make it work. Well, not<br>
always. But mostly. :-)<br>

</div>A quadcore could run LinuxMCE natively (non-vm) and then you could run a<br>
couple of Linux VMs next to it. You'll run into CPU load issues<br>
(possibly) if trying to record from all 4 inputs at once *AND* running<br>
the VMs because of the need to convert the analog data into some<br>
meaningful video format. Recording from one input and running a VM at<br>
the same time shouldn't be a major problem, depending on how the VM is<br>
configured.<br>
<br>
I run a MythTV client (not the server) on my quad-core at home along<br>
side doing lots of other work, including running VMs. My MythTV server<br>
is a single core AMD64 with a Hauppauge PVR-150 and a Hauppauge HVR-1600<br>
(dual inputs - one analog, one digital).<br>
<br>
I've never tried to run the server or client under a VM, however.<br>

</div>I can't be there - will be out of town. But best of luck getting it<br>
running.<br>
