Ok, I just thougth to this to avoid too many users complaints. Such as
"Why sound stop playing as soon as I seek in <Add a movie title here> ?" ;)
Well interleaved I think. Because I reencoded the coyote_ugly.avi to lower
resolution and it doesn't need -ni anymore. But with correct header no. 
Also is it normal that the audio avg byte/sec of the reencoded movie is 
different (I used -oac copy) ? In the original it's 176400 wich seems to be ok 
(vorbis bitrate + ogg overhead) and in the reencoded one it's 339448 wich 
seems to me a little too much. But the file still play good, so it certenly doesn't 
matter.
