Double Albums with MinimServer & Lightning DS

[simbun]

I might be barking up the wrong tree, but do you have the following configuration option set?

Code:

serverOptions: showAllDiscs=true

If you set it to false does it fix the ordering?

When it's set to true the xml tag originalTrackNumber has the value of the TrackNumber tag in the underlying files (in most scenarios), so multiple tracks will have the same value (on a multi-disc release), but when set to false originalTrackNumber is unique (1-total tracks).
My guess is that the control point is using this to sort the tracks.

When I first started using the WiiM app it had similar problems, until they fixed it by displaying the tracks in the order they appeared in the xml.

EDIT:
Just looked on the Lightning DS home page (I don't have an ios to test with) and it appears it indexes the files itself, so it's just using MinimServer as a glorified fileshare. This explains how it's incorrectly ordering the tracks (it's a bug in Lightning DS) but doesn't explain how it works with Twonkey...unless of course you just need to re-index Lightning DS after you'd added the DiscNumber tags.
