Why do I get a "Forbidden: error 403" message when trying to access Sprint live Tv on my Verizon LG Voyager? - rtsp　live

I typed the correct address, for example, rtsp: / / live.mobitv.com: 554/3-CDMA.sdp in the browser but I have my Voyager is prohibited: Error 403 "every message. Any idea what they do wrong? I installed the V05 firmware.
