I have never had any success controlling my 4250hdc (provided by BHN) until
I saw the email from Christian Szpilfogel linked above. That one can at
least get on/off/status. I have never had any luck changing the channels. I
can capture video though.

If I could change channels, I could actually use firewire as a source.
