As far as i'm aware, when you use anydvd it tries to crack every stream present on the dvd. By this i mean, from the main movie right down as far as somtetimes those stupid 2 second black shots that has no audio.

Anydvd needs a certain amount of info to crack each stream and becuase they are soo small it cannot do it, hence it guess'.

If you want these unimportant streams in your copy then don't worry because they aren't detrimental to the main move, which is always cracked (hopefully always, anyway) and i've never had any problems run them. With the new spy kids 3d i too get the same warning but copying everything, it all still works.

That's how i understand it, but if slysoft could confirm/correct, that would be great
