We have many pc’s at the moment who are no longer able to play help steps (videos). The error we see: “Your browser does not support the video tag”. See the included screenshot - the error in the right corner, next to arrow 4.
We have this issue on Win10 but mainly on Win11 at the moment. We use currently Rhinoceros 7.18.22x - but last school year we didn’t have this problem, but each year the machines get a new/fresh installation.
Is there a file or registrykey where we can change a value so this works for everyone?
I tried to copy the settings-Scheme__Default.xml file from a pc where the videos are shown to a pc where the videos wouldn’t play, and it still didn’t work. Maybe it is a combination of files/registry entries that solves it?
One of my colleagues found a workaround - but it only works for him, and we have a lot of students, not just a handfull, who experience this issue. He solved it by entering the ‘View’ menu and then select ‘Display Options’. In the ‘OpenGL’ segment change the value for ‘Antialiasing’ (to 2 for instance). And then save the setting and start Rhino again.

There are 19 service releases that came after the version that you are running.
I’d at least update this on one machine and see if that makes a difference.

You might also want to check into the Nvidia and Intel video drivers on the machines that work vs those that don’t. In any case it would probably not be a bad idea to update them all to the latest available.
