Some have come forward on this topic, but it is still not possible for JRiver to read my assigned disk numbers (see attachment - e.g. C103B) and display them in a column. I was hoping for a new library field to be added to JRiver. In the meantime, even after several updates and the new version 32, nothing has happened. Besides, I might not be the only one who names his CDs with letters and numbers. Other programs, such as Foobar 2000 or MusicBee, do not have any problems displaying the disc numbers as strings.
If I change the disk number from C913 to 913, the DISK# library field can detect this and also represent it. If I create a new library field DISK# and use the same parameters as in the library field DISK#, JRiver doesn't show anything. What's going wrong here?
