Playlists found and listed, but no content apparently!

[Blowers]

Hi,

I'm a relative newbie to Minimserver and am having a major problem getting my m3u playlists to play. They are on my QNAP NAS, as is Minimserver. They show up fine after scanning, but when I try to play any playlist on phone or iPad, I just get the error message: "Error fetching results. No item or container elements found in XML data".

The playlists play fine when I access them through QNAP's own beta UPNP server. Any ideas? My playlists look like this:    

Many thanks
