Hyperion integration - no longer able to select protobuffer input

Hi. Ive got an automation which selects the correct Hyperion input depending on the mode set on Logitech Harmony. Since i have upgraded my Hyperion to Alpha 10, its no longer possible to select protobuffer though - i can only select internal grabber (the system Hyperion runs on), or USB Capture.
I know this is mainly a question for Hyperion forums, but maybe someone here has already managed to find a workaround?
