Sorry dude, that is beyond my knowledge level.
You may have to wait for the dvd release.
Too bad, I found first episode with commentary online on some Portuguese site, but it has terrible quality and i also noticed that is not something really EXTRA. They are just repeating 5mins of episode and then Mike a Bryan talk about it for really only couple of seconds, then next 5mins of episode comes. Maybe it is not worth to care about it, but anyway, if you find something important in it, feel free to let us now!
