I’m trying to stream music to other computers and mediadevices on the network. I have 2 x W7 PC and 2 x W7 laptop. Laptops can pushmusic to other PCs and to media player, but PC’s won't, although they canreceive from laptop. When I select ‘Play To’ in Media Player, the dialog boxdoes not appear – well is does for a split second then disappears. PCs are 64bit with IE9, laptops 32bit with IE9. All settings checked and the same. Anyidea? Laptops are wireless, PCs on ethernet.
