Ahhh, good.  My drives in my PC-V1200 are cold to the touch.  They have
a 120mm fan blowing right over them at the very, very bottom of the
all-aluminum case.  All other components are

Huh?  What do you mean?  40 hours of ATSC equals about 350GB!!!

I have a NTSC TiVO and tape delay _everything_.  I like to catch things
later.  My wife actually uses it about 10x as much as me, but I like to
record sporting events.  Recording HDTV of live broadcasts of NFL
Football and Orlando Magic Basketball (when they are on the road, TV18),
would be nice, hence MEDUSA.

BTW, I goofed.  ATSC is 19.2Mbps (2.4MBps), not 19.2MBps.  So it's
already a pre-compressed digital signal.  QAM is similar.  But that
still results in about 8.5GBps/hour!  Hence why a 120GB HDTV DirectTiVO
only gets about 13 hours.

With 800GB is usable, that's only about 100 hours.

I basically want this unit for ...
A)  Favorite 40 hours of MPEG-2 DVDs (~350GB)
B)  Favorite 40 hours of ATSC HDTV (~350GB)
C)  Favorite 1,000 hours of 192Kbps/44KHz MP3 (~100GB)

I'll use additional MPEG-4 compression to compress HDTV or DVDs further,
especially if I'm going to stream them over the network.

It would also be a nice "live backup" of my server/workstations too. 
But I'll go 1000Mbps network if I do that.
