Hey Skylonxe,
Could you provide me with a bit more clarity, as your steps are a bit confusing?
I recently had a user reporting a similar issue with his project, and he resolved it by calling the Media Player to open in a different way.
Video Media Texture not Working
Could you perhaps convey what exactly you are attempting to do with your particular setup? There are always ways to do something differently, and perhaps the route you are taking can be done in an easier and more effective way.
Let me know if you have further questions or need additional assistance.
Cheers,
