I have been unable to stream my music to my PS3 since installing Windows 7 7100 x64. With Vista I am able to stream the media and the PS3 sees my machine as a media server. I have gone to the media player and told it to share my music and went into the advance settings. My machine is not part of a homegroup. I can't see the PS3 listed in the network devices to share to. Any ideas how I can fix this?

are you able to manually enter the IP address of the PS3?

There isn't an option in the media streaming settings to enter an ip address. My norton does pick up the ps3 in the network map and I have it set to full trust which are the same settings I used with vista. The windows firewall is disabled.
