There were other changes too, but I'm not sure which would be causing your issue. If you can get the parameters, what will hopefully tell where to look.
Have you confirmed that the ripped data from BASSCD 2.4.6 is correct, ie. it isn't just that 2.4.7+ is reporting an error that 2.4.6 ignored?
I'm currently still waiting on the MusicBee developer Steven to get back to me. Normally very up to date on bass library updates, basscd.dll stopped being included past 2.4.6 with the player with the comment that "newer versions do not work correctly with MusicBee." When 2.4.8 came out I tested it myself, and while it produces a rip that seems to play correctly with secure rip turned off, choosing secure produces error rates of +90% every time that stall when the "Trying to repair.." feature kicks in. Going back to 2.4.6 results in secure rips every time.
I have no way to check myself if the real issue is 2.4.6 ignoring errors, or the likelihood of newer versions ALWAYS reporting errors. Or if MusicBee itself is the culprit, but with thousands of users worldwide that would surprise me.
I'll "bump" the parameters issue and hope to hear from him over the weekend.
