are you sure you're using the same and current build as REPORTEDLISTENERS was removed in the RC builds and also there is no platform specific differences on the stats reporting as it would server no purpose and would completely defeat the whole point of the v2 DNAS acting the same on any platform it is run on.
http://wiki.winamp.com/wiki/SHOUTcas...2_XML_Reponses is pretty clear on what values are provided. i'd suggest re-reading and making sure you're DNAS builds are current.
