No. It should be the same for all three versions. That is the great
thing about Ralatable TRM. It's a psychoacoustic fingerprint that should
not depend on the encoding.

But read my other mail retitling the bug to an RFP. libtunepimp
(tp_tagger1) or even the examples from libmusicbrainz are better
suited.
