serverOptions: showAllDiscs=true (full license)

[Bicho]

Well, now I'm using the Trial.
I have added Advanced > showAllDiscs=true.
In jRiver if I load the "MinimServer library'' it does not show the Disc # tag.
If I directly import the music to a local library it shows Disc # correctly.
So, I think the Tags in the files are correct.
What could be happening?
In the Linn application it correctly shows me Disc# and separates the disks >> 1, >> 2, etc.
Apparently the Disc # tag generated by the minimserver is incompatible with jRiver.
Any idea how to solve this?
Thank you!
