This sounds a lot like you tried to mux together streams that had identical
serialnos. oggz merge ought to moan about trying to do this, maybe it does
not. serialnos should be unique within a physical stream (eg, a file), so each
component stream should have a different one. Usually, an encoder uses a
random number, which makes collisions unlikely.

Most should. Output from oggz merge should not be much different from
the output of another program which writes already muxed audio.
