Sounds like you've set the wrong frequency table in mythtv-setup (I'm 
pretty sure it's under cable).  My guess, you've set us-cable, but you 
need us-cable-hrc.

BTW, you should start new threads some way other than by replying to an 
existing message.  When you reply, your message gets buried underneath 
another thread (in mail clients that do threading properly).  I almost 
deleted your 3 messages (one on topic--in the hard disk thread--and two 
on other topics) because I wasn't interested in the hard drive topic.  
Most mail readers allow you to select an e-mail address and "compose 
mail to" (i.e. in Thunderbird, right-click the mythtv-users address and 
"Compose Mail To").  Doing so doesn't apply the headers that result in 
the message being buried in another thread.  And, if your mail client 
doesn't have similar functionality, there's always copy/paste of an 
e-mail address (or adding mythtv-users to the address book...).
