If you are using a Composite or S-Video direct connection from an
external source, such as a cable box or DVB box, you cannot scan for
channels, as the input is only receiving baseband video (it is not a
'tuneable' source).

To setup MythTV for use with such a setup, you can manually create the
channels you want to be able to record from the composite input, and
then assign either a real channel change script (if using an IR
blaster) or /bin/true as the channel changer if doing the channel
changing manually on the DVB box.

If you are using an IR blaster with your DVB box, you need to ensure
that the freqid field for the channels assigned to the DVB box video
source contain the correct channel numbers (that you normally enter on
the DVB box's remote control) so that the IR blaster can change
channel automatically when it needs to record. This is the method I
use to record from a digital cable box that outputs composite video to
my PVR-150/350 cards, using a serial IR blaster. This method also
allows you to use normal program listings (if available in your

If you are not using an IR blaster, you need to create a single
channel assigned to the DVB box source. You will change channel on the
DVB box manually, and MythTV will record whatever video is being
received. With a single channel, you do not use normal listings, but
you can manually schedule programs and give them appropriate names.
