=8 total streams

I've had all streams going flawlessly on multiple occasions with no loss 
of quality, jitters, pauses, crashes or gremlins of any kind.  A typical 
HD 1080i broadcast, I believe, clocks in around 15 mbit/s.  More if it 
contains multiple streams, but a HD3000 only records one stream at a 
time in Myth so that's irrelevant.  Granted this is all going on through 
a gigabit lan, but a 100mbit lan should be more than enough bandwidth 
and possibly even your newer 54 mbit and greater wireless lans.  For 
your average 7200 rpm drive that has sustained read and write rates of 
about 30 MBytes/s, multiple HD streams should barely be a flicker of 
activity for the drive.
