I couldn't agree more, I think 8 tuners will definitely be overkill. We
get by with 3 in the house. I have 2 on the primary (family room) machine
and 1 on the slave backend. I have them setup as tuner 0 (primary) tuner
1(slave) tuner 2(primary). This gives me the abilty to have 2 tuners in
use but on 2 separate machines, allowing me to still watch livetv in
family room with all the Myth features.

It is a rare occasion when all 3 tuners are recording something, and in
that case we tend to start watching a recording before it's finished and
FFW through comm breaks anyway.

Even with a single tuner pointed on the Sci-Fi channel 24/7. You probably
wouldn't need 8 total. You'll have way more television recorded than
you'll have time to watch. Even with 4 tuners recording hour shows up to 4
hours a day you already have 16 hours of TV to catch up on. Holy crap, I
wish i had that much time to veg.

My suggestion would be to start with a few tuners, see if it's adequate
then  build up if needed. But I do see the "My wife says it's ok now"
thing.... gotta get it while you can.
