He's not actually talking about the stream output itself; he's talking 
about the sector size on the CD. Since a track boundary can only be on a 
whole sector, but a sector consists of a bunch of samples, there can 
still be gaps between tracks. He wants a way to split a Vorbis file 
exactly on one of these boundaries so one can break a single file into 
multiple tracks, but still have the audio line up absolutely perfectly.

At least, I think that's the case with a CD, Monty may show up and prove 
me wrong.

Anyway. He's not starting with something he ripped from CD, he's 
starting with a recording he wants broken into tracks.

As I noted in my other email, I think applications of Nero take care of 
this transparently (perhaps by nudging tracks over a couple sectors and 
performing other magic to make them seamless)
