We can find the problem, I'm sure.

Sounds interesting.

I did not find a zlib directory in opendem/src/q3a/opendemo/game/ and we don't
have a opendemo/game directory at all. So did you check it in already?
I would prefer opendem/src/libs/zlib as a more generic place.

So you used the standard zlib interface, which reverts to the plain file
behaviour, if the file was not compressed.

You're brave!

I think odFread() should be replaces by gzread() and nothing more. This can
easily be done before or after the ring-buffer comes in place.

My ring-buffer comes along nicely, the code is completely typed in, compiles
without warnings with GCC and qvm and does not crash, but it doesn't do
anything useful yet. I hope for a bit more debugging time over the weekend.
