How can I open a VLC stream?

Hi, I am trying to open a stream served by VLC on the same box as PMS. I feel like i have tried every combination that VLC is capable of but nothing is working.

I know VLC is streaming correctly since i can access the stream via safari (tho it just starts downloading as a file) and via VLC on another computer (however no sound, but im not concerning myself with that now)

VLC offers 4 kinds of streams:
HTTP
UDP
MMSH
RTP

surely plex ought to work with at least HTTP. I tried replicating what the EyeTV plugin is doing to open it's http stream which is: return Redirect('http://127.0.0.1:1234')

I have also tried this:

def MainMenu():
	dir = MediaContainer(title1="VLC Player")
	dir.Append(
		VideoItem(
			'mms://127.0.0.1:1234',
			title='Play Movie',
			subtitle="Click to open this stream!",
			summary="VLC"
			)
		)
	return dir

sometimes I can get an infinite "Opening stream box" and have to force quit plex. most of the time nothing at all happens.

the logs are usually void of anything, but some combinations of VLC options do get plex to show a 302 with 0 bytes in the log.

Long story short: does anybody have a clue how to stream from VLC to plex?
