To view in dBpoweramp: If you are using a dBpoweramp version which shows tags (I'm paying, don't know if the free one can), it should come up just as any other tag. If not, you try to view it in fb2k. That's view, not scan. To view, you can e.g. choose the track, Alt+Enter, and then view the Properties tab. Alternatively, try Mp3Tag (free).
