My guess is that even if you manage to get t' NP30 working at all using LMS as a server, that playback will be glitchy & you may even find that your player hangs or crashes too & you may have to perform factory resets to restore it to stable operation.
Your NP30 works as renderer using DLNA/UPnP media server S/W & you'll need to install suitable software on whatever you're currently using as a server instead of LMS (you don't have to uninstall LMS if you are still using your SB Classic elsewhere) i.e. your pooter /NAS.
I know that that LMS can prolly be seen as a 'Network Share' on your NP30 once you logged it on to your network & I guess this is what has foxed you into thinking you can continue to use it with the Pioneer. I've recently jumped ship from running SBT's myself & my C.A. Stream Magic 6 is also a UPnP/DLNA streamer like t Pioneer. When I first set it up I did try it running from LMS out of curiosioty & yes I did get it to play but experienced all the previously mentioned SNAFU's. However properly set up & running from the correct server S/W it's completely rock solid & stable/reliable. :^
If you're running a NAS there will prolly be a UPnP/DLNA S/W package available from your NAS mfr....there may even be one pre-installed, as there was on my old Netgear ReadyNAS. On my new Synology DS213 you download it from the package center so just a couple of clicks & you're done. If you're using a PC/Mac as a server, I can't advise other than do a search for UPnP/DLNA server S/W or ask peeps on here re any particular good ones.......with the caveat that Twonky server S/W is prolly best avoided as it has a fearsome bad reputation. :td:
Here's a couple of linkys to recent threads which may be of use. covering some aspects of UPnP/DLNA media servers/renderers + suitable NAS's etc.

Finally......controller App for your NP30......Bubble UPnP for Android devices is wot I use & I think its brilliant......easily as good as Squeezebox Commander which I used with my SBT's, which is a very good App.....I actually prefer Bubble UPnP & I wuz more than happy with SB Commander, so I'd say even better than this IMV.

Bubble cost around £3 for the paid licence....there is a free version with Ads but the functionality is fairly limited & buying the licence is a real steal.
I've had a similar offal experience re C.A.'s Android controller App which is completely feckin' hopeless....a real POS in fact & even when it works properly t' functionality is fairly limited:doh: :td: ......yes I did mean offal ;-)
You'll have ter excuse any typos until tomorrow as I've only managed to get access to the site again just now & I'm off ter bed. :zzzz:
