I recently upgraded to Win10 and chose FLAC. Not sure how the output format would have much to do with whether or not CD info can be found.
By the way, I haven't been able to repro it with any CD recently except this particular David Gilmour CD. (and to add to the confusion, I happen to have that Keith Richards CD, but haven't yet ripped it...will be interesting to remove the errant gilmour, rip
the richards, the rip gilmore again)
I will change output format to something/anything else to make sure that isn't an issue.
