Yep it is broken VERBOSE(). I'll fix that shortly.

One way to handle #2556 might be to ignore alternative video
streams once we have found a valid stream. Perhaps using
the stream type as a preference.

Currently we are using the stream with the lowest component tag,
but it seems that the one with the highest component tag works for
2556.

The PMT debugging printout says that it'll use the first video
stream found, which is contrary to what we do. Is there a situation
in which things would break if we chose the video stream in this
way?
