MinimServer & Naim NDX/n-Stream Playlists errors

[stampie]

To aid deciphering this problem, I have attached two debug logs.

Playlist unavailable - this displays what minimserver is doing when selecting a playlist in the naim app that results in 'tracks unavailable' message

Playlist working - minimserver log when selecting a playlist works correctly.

192.168.0.102 - IP address for NAS
...113 - iPad running naim app
...110 - naim NDX streamer
...109 - Windows laptop (only running minimwatch, don't know why showing)

NB: All these are running with fixed IP addresses assigned by Asus router.

btw (I was playing The Who Live In Leeds at the same time, which may account for some of entries)

Perhaps Simon can shed some light on the root cause for us
thanks
Nick
