Been discussed on this list and the ivtv list in the past, also in ivtv 
docs, IIRC. DVD-Special 2 is the one Microsoft XP Media Center Edition 
uses, and thus is the one that gets the most attention in the firmware. 
Its generally recommended as the best one to use (I use it myself on 
all my cards).
