As the other guy said, metadata is part of the file, it's embedded with the music within it's container... a device cannot invent something that isn't there, and I've never seen a device do an auto-translate over a setting.

As I've never use Fairstar, I can't speak about it possibly doing something weird to the files, but I'd still say that it's the best explanation.
I usually rip CDs with WMP and if I need to convert to MP3, I have Audio Converter Pro (but it's a bit dated now, but still a great convertor), and if the metadata is off, I correct with MP3Tag, never had a single issue with this approach.
