RTSP not working, ideas?

Any ideas why this test rtsp feed isn’t working in the PlayMovie node?
rtsp://admin:admin1234@96.71.29.17:1053/1
Main profile is h.264 (/0) , substream at ( /1, /2).
Note if you are reading this weeks after submit date, the feed may have been taken offline.

Your RTSP feed doesn’t work in Vuo 1.2.8 but does work in our version under development, so it’s likely the same problem as this bug report.

Thanks.
And yes, I was able to confirm it works with VLC.
