[mythtv-users] Questions: multiple HD tuner backend with Pentium 4 3.0 GHz front-end

Again, thanks for the help. This is more of a progress update. It'll be 
slow going before I'm up and running.

Okay, got my 2.8 GHz CPU installed and found a PSU to run it on a 
motherboard... didn't start... :( I did have a 2.53 GHz CPU though, and 
that works). My motherboard has *no* network port at all, but I do have 
a gigabit ethernet card. I think I've used it in Linux before. It's a 
Netgear GA311.

Turns out my RAM was actually three 256 MB sticks of PC2100/DDR266. So, 
I put in two sticks for a total of 512 MB, and installed Mythdora on a 
3GB and 8 GB pair of hard drives. Then my brother came by and we had to 
do some other computer stuff (getting Windows XP installed on a couple 
of old machines).

So, my backend is working... still no tuners (other than the two Theater 
550 cards that I have but won't work under Linux).

That's good, because I just knocked it down to 2.53 GHz.

Well, I hope 512 will do. If not, I guess I can switch to this DDR 400 
I've got.

What's SD? Schedules Direct? Is commercial flagging a frontend or 
backend CPU hog? I imagine that I could run that as a job on either 
after the show has been recoreded.

The MythDora install was cake, for the little bit that I did. I'm really 
liking Fedora 8 though. I might try an installation of MythTV on it. 
Thanks for the tips.
