I have a niche CD (ABRSM Exam Pieces for Grade 4 Violin) which VLC obtains all the track titles for from CDDB, but RipperX doesn't like - it gives an Error 23 CD not found in database pop-up.
I've tested Ripper X with another CD just to make sure it's ok, and it is. It's v 2.8.0 in case that's important. It's configured by default to use:
gnudb.gnudb.org/~cddb/cddb.cgi
I've tried to get Ripper X to accept other CDDB databases like the one VLC uses:
freedb.freedb.org
but then I get the error 20: unable to connect. Could be the URL, could be the wrong protocol, I don't know :(
