The reason in the commit log (and I remember this
well, because I was bitten by this commit myself) was
that it is to prevent channels with marginal (or
non-existant) signal strength from being put into the
lineup.  My guess for this is because I've read on the
list (though have not had problems myself with this)
that MythTV has problems with weaker signals.  (I
wouldn't know how strong the signals I have are, since
I'm using a FusionHDTV 5 Lite, and the kernel outright
lies about the signal strength).

Now that you mention it though, I just noticed that
I'm missing 9.4 (one of the PBS channels) as well,
most likely because of the time of the day that I did
the scan.  This is only a minor annoyance for me at
the moment, but one nonetheless.
