Ummm...  Channel change script.  If specified, MythTV doesn't change the
channel, it runs the script.

If you mean you're unplugging the STB from composite to record something
from, i.e., a VCR, that's not the same video source (and, therefore, has
different--i.e. only one--channels).  You need to fix your
configuration.  Search the archives for explanations of how to do this
(and why--in most any case--using some tool other than MythTV to do the
recording is more appropriate).

Think that over...  You configured MythTV with mythtv-setup, where you
specified Input Connections.  There, you specify which video source is
connected to which inputs (and you specify things like the external
channel change command...).

You don't.  If it's available on multiple inputs, MythTV chooses which
input to use.  If it's /not/ available on multiple inputs, but MythTV
thinks it is, you've misconfigured your system.
