Try this. Deselect all tracks except track 1, then proceed. If you can rip track 1 OK, then go back and select all tracks except track 1, then proceed. If that works you can then combine the contents of the 2 folders into one.Not sure, they play okay and the album details and tracks are all showing before the 'scanning chapters' gets stuck ....very strange.
I've had this trick work a couple times in the past on a few problem-some rips, hope it works for you.
