I have the xtr-16 in the video from Jimmy and Cheetahstand sent him a new one. I tested and tested it and it works just fine with my setups. Not sure why it was not working for him and he got a replacement and then returned all his stuff back for a refund.
I have 3 Canon and 1 Nikon X1 transmitters, and numerous XTR-16 receivers. I have not experienced any issues with the Nikon X1 transmitter and XTR 16 combo, when making power changes or when turning individual Groups On or Off but, all 3 of my Canon X1's do have issues with transferring power changes when using the XTR 16 receivers. It is especially annoying when trying to turn individual Groups On or Off when using the Canon X1's. In the video it looked like he was using the "Test" button to transfer the power setting in the X1 to the XTR 16 receivers. I found it more reliable to just double press the "Gr" button in this situation.
The best solution I found when using flash units with the XTR 16 receivers and when using the X1 transmitter is to mount an XT-16 transmitter in the hot shoe of the X1 and use the XT 16 transmitter to control the flash units with the XTR 16 receivers. Or if you're going with a manual only setup is to use an XT 32 transmitter in lieu of the X1.
I am not sure if Godox will fix these issues with a future firmware update but since I refuse to update my X1 transmitters past v12 I would never know nor do I care, because using the XT 16 or XT 32 transmitters, as I have described above, has solved all my issues and given me one less things to worry about. Which reminds me, I need to order another XT 32 transmitter.
