Figured as much, but I wanted to make sure.  I guess I should have added 
to the initial post that I had searched the archives but, either I 
wasn't using the right search phrase (too specific?) or something, but I 
wasn't sure the answer I found applied to the current release of mythtv 
that I have installed (atrpms), and the answer(s) I did find seemed 

However, thanks for answering nonetheless! :)

I'm leaning towards upgrading the backend system to help improve 
performance.  I was looking at the DB because it was taking several 
seconds to bring up the recordings page, and, in some cases, it would 
take 15 seconds (or more) to navigate through the recordings.

Granted, my backend server is using 7200rpm IDE drives for the 
recordings directory, and I've got 5 tuners on it (three PVR-150's and 
the two tuners from an HDHomeRun), 3 frontends, and I run mythcommflag 
after the recording completes.  I'm suspecting that it is just too much 
for the AMD64 3400+.. sar's not showing a lot of I/O contention all of 
the time, but it does creep in there, and the load average hovers 
between idle and ~80% (at times).  I haven't even attempted transcoding 
the HD streams yet.
