      1. We need to know what version of Isadora you are working with.
      2. What is the source of the Syphon feed?
      3. Is the source of the Syphon feed actually generating continuous frames, or is it just sending that still test image once and then not outputting further frames because nothing has changed?
      4. Have you tried playing a video over that Syphon source rather than just sending a still image?
      5. Can you send a screen capture of what happens when you click on the green text to the left of the name of the first input of the Syphon Receiver actor so we can see the list of sources?
      6. Have you tried switching the server selection on the Syphon Receiver to something else, then back to your desired source?
      7. Have you tried adjusting the 'alpha mode' and 'keep alpha' inputs on the Syphon Receiver actor?
      8. Can you send a screen capture of what happens when you click on the source selection in Syphon Recorder?

        4.0.2, but also tested on 3.2.6, same result.

        What is the source of the Syphon feed?

        Output from 'Videosync' software which runs in Ableton, outputs to Syphon by default, have used identical setup often, also vice versa, which still works fine...

        Is the source of the Syphon feed actually generating continuous frames, or is it just sending that still test image once and then not outputting further frames because nothing has changed?

        continuous frames. have tested with multiple clips

        Have you tried playing a video over that Syphon source rather than just sending a still image?

        yes, see above

        Can you send a screen capture of what happens when you click on the green text to the left of the name of the first input of the Syphon Receiver actor so we can see the list of sources? 
        NB: i also have tried sending through these return tracks. Seen by OBS/Syphon Recorder, not by Syphon Receiver

        Have you tried switching the server selection on the Syphon Receiver to something else, then back to your desired source?

        yes, if you count the return tracks. i don't have any other syphon sources for testing.

        Have you tried adjusting the 'alpha mode' and 'keep alpha' inputs on the Syphon Receiver actor?

        yes, no result

        Can you send a screen capture of what happens when you click on the source selection in Syphon Recorder?

            thanks, sadly no. In my pic 'Main' is not visible in the window, but it stays selected in the actual situation. This is just because it was an awkward screengrab to make.

               I'm not sure what you mean by this. In which window is it not visible?

                  NB: i have tried with/without Alpha. Also restarting after changing settings. I got a nagging feeling it's related, but I can't nail it. And why does Syphon Recorder have no problem with it? Grrr

                  Also - thanks for taking the time to check out the other software.

                    I sent you a direct message yesterday. I'd like to set up a video call at some point so I can see this for myself and maybe try some things that might not be occurring to me because I'm trying to solve this theoretically from a distance rather than being able to futz with settings and such myself.

                      Note for other users:

                      After a video call with the user I was unable to determine why Isadora cannot receive Syphon video streams from Ableton Videosync, but we were able to get Syphon video from other software on their computer into Isadora, so there's something funky about how Ableton Videosync is sending out Syphon video streams. (The Syphon streams do show up as options in Isadora's Syphon Receiver actor, but no video stream is sent out to other actors from it.) The user is following up with Ableton to see if they can get any information about this and in the meantime, I've helped them set up a workaround using the Screen Capture actor.

                        Which version did you try of videosync ?  I can receive in Max with the try version, but i can't send it from Max ....

                        I believe the try version of videosync doesn't work perfect with syphon
