Hi Josu...
I'm not really sure how well my Debian / Mythtv experience translates
into advice, but here goes...
I am running two Debian computers. Both have back and (usually) front
ends running. Both have two PCI HDTV ATSC tuner cards. Both have
nvidia graphics.
First off, having two back ends is probably not such a great thing. For
one, I don't know which box can burn a particular show (I am lead to
believe DVD burning can only work with recordings on the local machine).
And, yes, I know I can cross mount the recordings directory. But I
don't want to tempt fate. That is, I am not all that sure I will not
end up recording a show on an NFS mounted drive (I think back ends can
auto-magically find NFS mounted recording directories). What a way to
wipe out your humble home band width.
Second, I have always (did I mention always) been suspicious having two
back ends causes no end to mysterious program erasures. More then once
have I seen programs recorded then immediately erased. I believe the
back end which happens to record the show is out of disk space. I have
learn not to trust the system status reports (i.e. you have 10 hours of
recording time left). Its too late to recover missing shows, but when I
see new shows disappearing, I immediately start manually deleting shows.
No telling which machine they are stored on though. So I just keep
deleting until I figure both back ends have ample space for new
recordings. Which leads me to...
Third, with two back ends, I can never tell, from a front end, where a
recording resides. So, if I think I need to free up space on the master
back end machine, I really have no way of telling which shows I need to
delete. I just delete anything that ends up on the bottom of the "I
must watch this" totem poll. That usually holds me for a week or two.
Also, knowing where a show is would make deciding which back end to burn
DVDs on a bit easier. As I said it is a trial and error thing when I
want to drop a recording to a DVD. I just try and if I can't find it I
try the other back end.
As far as a remote, I never got enough support to get the remote on my
turner card to work. I even kept the wiki up to date on the darn thing
hoping that might be of help. I just use a cheep IR keyboard connected
to the PS/2 port of my PC. Nothing special to set up. No LIRC to
configure. No JP1 remote reprogramming. It just works. Not to mention
its darn hard to hide it between the couch cushions.
I think everyone here will agree liveTV is not mythtv's strong point.
It usually works for me, but I've had times when it hiccups. It might
have been when I happened to be using a tuner on the "other" (far) back
end. As I don't usually watch liveTV it is difficult to recall what the
circumstances might have been when it failed.
I'm running Debian unstable and, like you, using the debian multimedia
repository. The master back end is on a quad core and the slave back
end is on a dual core system. The master back is also running other
services like CUPS.
-good luck
