First off, I'm mainly converting .MKV to Apple TV, so my questions are directed at that. Now i've read a bunch of posts, with different preferences. So my first questions is, is the "2 pass option" necessary? second, how do i get the videos to be fullscreen on my HDTV? it's widescreen. with the black bars on top and bottom. Is there a way to rid this? Third, what are the best setting for visualhub for Bluray .MKV files? please explain in detail. Thx and please reply!!
