Empty UPnP Recodings/Music/Videos folder on Samsung TV

[Valentin.Vidic@…]

After upgrading to 0.28.1 UPnP browsing with Samsung TV (F6500) stopped working correctly. MythTV was still visible in the device list and the first level of directories were displayed: Music, Recordings, Videos.

Entering any of these directories however displayed an empty folder. The problem seems to be that Samsung TV sends a first browse request with a RequestCount? of 1 and breaks if there is more than 1 result returned.

So for example in the Music folder 1 result is requested:

POST /CDS_Control HTTP/1.1
Accept: */*
User-Agent: SEC_HHP_[TV] Samsung/1.0 DLNADOC/1.50
Host: 192.168.0.1:6544
SOAPACTION: "urn:schemas-upnp-org:service:ContentDirectory:1#Browse"
CONTENT-TYPE:  text/xml; charset="utf-8"
Content-Length: 455

<?xml version="1.0" encoding="utf-8"?><s:Envelope s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">

</s:Body></s:Envelope>

but MythTV returns all 4 available elements:
