Problem with checksums
...ues and the page body to the CRC procedure. I even use the same look up
table in the CRC algo as is used in "framing.c". Still it deos not work.
Is there anything else I have to do?
Thanks,
Erik

Checksum question
I'm trying to simply regenerate the comment header checksum on the ogg
file "test.ogg"
I ripped the checksum function from libvorbis, and only modified it in
that I hard-coded what I think is the comment header (as far as I can
tell from the docs). However it seems to generate an invalid checksum
(according to ogginfo)
Here is a url to the two files, please help :)
