[Vorbis] storage format question.

Thanks for the reply,
I have added some more info for future reference based on some more 
reading.

I read some documents on the ogg bitstream format (RFC3533) and it 
appears that one cannot simply do a hex-edit and randomly cut the 
bitstream.
The ogg bitstream contains a Beg_of_Stream (bos) page at the begining of 
every stream, which has important info on how to decode the stream.
If one removes this page, it will be difficult (if not impossible) to 
play an ogg file (containing vorbis encoded data in this case).

Actually, I think it is not required to store vorbis encoded bitstrean 
in ogg containers. One can just store it as is, but one will have to 
make a seperate decoder for that..
Please correct me if this is wrong.

The term "Ogg Vorbis" just happens to be a good combination for 
describing two different things. Ogg is a completely independeny 
container format (that can carry any bit stream) and vorbis is just an 
example of an encoder that happens to use Ogg.

The best reference, that describes the ogg bitstream format in detail 
is rfc3533.
