I have a Slingbox Pro-HD and can connect just fine with my Windows 7 machine. On the same network I have a Mac Mini and and Macbook that I can not connect to the Slingbox. when I log on on slingcox.com it finds the Slingbox, but is can not connect to the Slingbox. Any idea? I have tested with the firewall off on both Mac's and still does not work.
