[Vorbis] ov_open_callbacks takes so much time to open 210 MB OGG file

Thanks for the info. I will try to reproduce the bug with use of: 
libvorbis-1.3.3\examples\vorbisfile_example.c .

I am not sure what that means.
I just try to append new OGG file to existing OGG file. Do you think, 
there is a bug, that the new OGG file is not appended into existing OGG

At correct position?
