Just a follow-up, the most you will ever see out of a single tuner is 
around 36Mbps.  That is recording every broadcast on a single QAM256 
cable channel, which means 3 HD channels, or a dozen SD channels.  For 
pure sequential access, a modern 2TB 5400RPM drive will top out north of

1Gbps, and won't go lower than 400Mbps.

Raymond,

Thanks for the info.  I'm a newbie, so I'm not quite clear on recording
multiple channels (HD or SD) from a single tuner.  Can someone
elaborate?

Thanks!

P.S.  I love the debate here.  I'm new to all this stuff, but I'm
learning quickly.  I have been spending HOURS reading about this stuff.
I'm always willing to accept the fact that someone else might know more
about something than I know.  So please don't take offense to something
I write... I'm really just looking for information (except for the
phallic references, of course). ;)
