Hi, sorry for the late reply.
We did not test it so far for multi-site installations. But it should work anyway! Please tell us your experiences by [email protected]. Thnx a lot!
You can use it for different sites at one time as you are working with a login that identifies you as one user. You will see all videos everywhere you log in with your data. If this is not a problem it is multi-site enabled. If you do not want to show all videos in each installation simply log into our plugin with different mail addresses. So only the mail-address is able to see the videos done with this login. By this you can separate it.
Does this information help?
