I imagine that this is all TV-specific, so it would probably be best to
be able to change it to any one of those.

Looking at the cec-client source, it seems to default to
CEC_DEVICE_TYPE_RECORDING_DEVICE

When my (Samsung) TV starts, it sees the RPi connected via HDMI and
defaults to the basic HDMI input. I have to use the source button on the
remote to switch to the HDMI-CEC input so that the remote buttons are
passed to MythTV.

Therefore, it would be useful for MythTV to tell the TV to switch to
that input automatically. This seems to be possible from cec-client, so
I could probably add it to my frontend launch script, but if MythTV
could handle it, it would be more convenient.
