Lots of changes to xiph.org/container/.
document now looks pretty good. I will have now to write some howtos and
organize Ogg specs and then link them all.

-Ogg essentially says, specify the bare minimum amount of information and let

-for. The disadvantage being that in terms of implementation the demuxer becomes
-dependant on codecs.

-Matroska on the other hand says 99.9% of codecs and all currently used
-codecs won't be limited by it and those are the only ones we care about, so
-we are going to specify as much information as possible in a standardised
-way, so the demuxer never needs to ask the codecs for any help, because the
-muxer has already gathered all the information it might need and stored it
-in a standard way for the demuxer to use. So the demuxer doesn't ever need
-to ask a decoder for codec specific information.

-our tools.
+Matroska, unlike Ogg is complex. Seeking in matroska is fast as compared to
+that in Ogg. You can use features like menus, chapters etc in Matroska.

-able to become a real alternative
-for codec developers, and for all platforms, thats why for the time being
-we are working on porting Gstreamer
-to win32 ( and later Mac OSX ), and will define a simple but powerful codec
-API, wrapping the gstreamer
-plugin API, so that developers can start to make their own codecs, just
-like what happenend with DivX and VfW
-( VCM ) years ago ( and even works with Speex via the ACM codec that was
-made for it ), so they can put their
-own streams in the MKV container. Based on that we are planning to make a
-nice editor also, but lets first
-get the basic framework working.
