MY blackberry (running the Bolt browser) come back with a "URL could not be found", then tells me it tried looking up "http://..." even though I types in rtsp://...
I'm using the same DynDNS domain name I created for the Apex.
It is my business phone and we do have a draconian ITS department, though they are not blocking access to my apex on the phone as they do at work - I don't know about rstp.
Alan, I get the same error with the URL you sent me. It seems lioke the BB wants to add "http://" in front of the rtsp address I type in.
