This isn't a great solution, but it will allow you to determine which
channels are output over firewire without reloading the modules

So simply start live tv on a channel that works, then manually using a
channel changer script on the command line, cycle through the channels
you're interested in. If you land on one that doesn't work, use the script
to jump back to the working channel within 5 or 10 seconds and you won't
kill firewire. As I said this isn't a great solution, but I have so few HD
channels that it's easy enough.
