Denon AVR X-1000 and the Pause command

[HCau1]

I have a Denon AVR-X1000 working well with Minimserver for MP3 and FLAC files. One last thing to sort out. The Denon pause command doesn't seem to work. For the (custom) tags to work perfectly it is necessary to transcode FLAC to WAV.
I can stop the WAV playback, I can even time seek backwards and forwards but I cannot pause playback. This seems to affect both MP3's and FLAC/WAV. I contacted Denon and they said (after some deliberation) it was a server problem, strikes me as strange but after some prodding, they indicated that AssetUPnP could pause (sort of ). I checked but then the format was transcoded to LPCM (the official DLNA minimum audio format).
In the end the Denon solution was to use WMP and a FLAC plugin from XIPH.org. and it worked ! so FLAC files can be paused via a network with Denon, however that was a very complicated and messy solution and needless to say none of the Minimserver functionality we all like so much.
Is there any way to adapt Minimserver so that the Denon Pause function can work (sorry for the long post, but this has been going on a while with Denon).
