Stream 'http-user-agent' command

Hello, I have a video stream that plays fine in VLC but on some models of Roku devices the stream glitches so I was wondering if anyone is familiar with using http-user-agent? I would like to set http-user-agent to VLC if possible but I do not know the proper code. What user agent does the ROkU 3 use compared to the Roku Stick? The stream works on Roku Stick but glitches on Roku 3.

Can I just change "<userAgent>http-user-agent=iPad</userAgent>" to be "<userAgent>http-user-agent=VLC</userAgent>" instead? I think VLC uses NSPlayer/7.10.0.3059 but not sure of the proper syntax to use with the Roku code. Thanks
