The OP asked if his hardware would handle 4 tuners/4 frontends.  Yesterday,
I was able to watch 3 different things, record 5 different things,
commercial flag 2 of the 5 recordings - simultaneously, on 7 year old
hardware.  I was recording to 1 LVM comprised of 2 ATA 133 hard drives.  It
seems to me that if that won't push it too far, then I don't know what
will.

I think we need a better definition of "like crazy" and "a lot" before we
build systems around it.
