In my previous reply I missed some of your points

do you really consider a sane approach having to update your code
when a new format comes out? I absolutely disagree.
In my opinion a sane format doesn't need any update when a new
content type comes out

and how do you keep correct sync if timestamps are not perfect?

I don't know anyone with that name.
None of us accept dogmas; when some of us posts or commits bad code he's 
immediately flamed,
whichever his name. Evidently you don't follow mplayer-dev-eng to see it 
with your eyes

we swear against any stupidity we find in content we have to deal with, not
particularly against ogg
