Is anyone using the Hotspot feature to listen to music over wifi with the Zune HD? Are you having any issues? When I go to play a song from the Zune Marketplace, I get the error "The item is missing or can't be played". This happens on 9 out of 10 songs I want to listen to. If you queue all of the marketplace top songs to play, then after going though a few songs it eventually will start playing a song. The Zune is definitely connected to the hotspot as album pictures and info will load. I can also download songs. When I connect the Zune to my home wifi, all of the songs will stream without issue so it appears to be a connectivity issue when using the Thunderbolt as a Hotspot.
