Hmm, you mention you couldn't hear any difference even
at -q0 with that file, so it could also be that Ogg can
encode it perfectly with a minimal amount of bits :)

I'm confused about this. I thought RC3 was supposed to be peelable,
but there was a mail from Monty a few hours ago claiming they
As far as I understand, peeling is equal to encoding at a lower
bitrate. i.e. no quality loss.

EAQUAL is principally flawed for doing comparisons between different
