mythbackend has "got hold of it". Shut down mythbackend and then try
to configure it in the card setup screen and all will be well. Once
you have it configured there is a setting somewhere which prevents it
being used as soon as mythbackend starts. I can't remember where that
setting is or what it's called but if you go through the setup screens
you will find it. Or someone else may remember it?
