Are you sure?

.../mythtv-0.18.1/contrib/6200ch-README
"6200ch is a small program that Stacey Son (mythdev at son.org)
wrote to change channels on a Motorola DCT-6200 cable
box via a 1394 (aka. Firewire) connection."
# 6200ch <your_favorite_channel_number>

I was under the impression that this functionality was added
in 0.18.1 as an internal app instead of an external config/shell call.
He implies that it is not for capture ... just channel.
