I need to open a URL in Quicktime player

I have been trying to get a script that opens a URL from my QSS :

set path_ to “rtsp://”
tell application “QuickTime Player” to open file path_

This seems to go to the right place but the file fails to open with the message "The Movie could not be opened’

Any ideas please

Hi and welcome.

I don’t have the latest version of QuickTime, but in older versions, you’d open a URL with the StandardAdditions’ ‘open location’ command:

set path_ to "rtsp://" 
tell application "QuickTime Player" to open location path_

Thanks that worked a treat
