I'm trying to get this going for Crestron control via IP, so far I can register the control system as a remote, but no success so far with commands (POST is hard).

Authentication port is 50002 for the BDP-S380

here's the command:

GET /?action=register&name=DeviceName&RegistrationType=initial&deviceId=MediaRemote:MA-CA-DD-RE-SS HTTP/1.1\nHost: Blu.Ray.IPA.DDR\n\n

remember to do this after you hit "start registration" on the player, or you'll get a 403:Forbidden

Commands are issued to port 50001, but I've not gotten the syntax right. Wireshark lists it as a POST followed by SOAP XML:

POST /upnp/control/IRCC HTTP/1.1\ncontent-type: text/xml; charset=utf-8\nsoapaction: "urn:schemas-sony-com:service :IRCC:1#X_SendIRCC"\nHost: Blu.Ray.IPA.DDR\nConnection: Keep-Alive\n\n

Followed by XML code I can't seem to post here.
