Kinsky only playing single tracks

Hi

New to the forum and need a little help with Kinsky - thanks

My setup

QNAP TS-210 NAS - Running Minim Server or Twonky V7
MacBook Pro - Kinsky installed
Renderer - Sony BDV-E380

I am have trouble getting Kinsky to play more than one track even though a full album or play list is showing in the Kinsky play list. So I have to manually double click to move on.

Volume control and advancing the play on the current track all works but 'next track button' is greyed and therefore not working.

Is this a limitation with control of the Sony or something else.

Appreciate any advice.

Bryn
