I reencoded an avi with mencoder some.avi -pass 1 then with -pass 2. After 
the second pass the image quality is better but I get image errors between 
the scenes (when the screen goes black. Its the StarWars Breathing teaser). 
Instead of a black screen I get "snow" like when you turn on the tv and don't 
select a channel but in colour and not the whole screen is covered, its just 
some spots. (If you need to see it i can upload a sample).
