I figured id post this since im sure there may be others having this issue. I had an older Slingbox av.. I went on the singbox webstite for setting up you slingbox to view via the web.. During the process it updated my firmware. Whatever the online setup did, It worked. I can now stream the AV to my motorola droid.
Hope this helps someone
Your symptoms are usually indicative of both TCP and UDP ports of the Slingbox not being port forwarded.
I would recommend that you go back into your router's port forwarding rules it is port forwarding both TCP and UDP of your Slingbox.
If you're still not able to connect remotely, then it is possible that the port is either being block or used by the remote location's hotspot. In which case, I would recommend trying to change the Slingbox's default port 5001 to a more common port like port 80 (HTTP) or 443 (HTTPS). If this is necessary, then you'll need also change the port forwarding rules to reflect the changes you've made to the Slingbox.
