Can I use two Media Players to switch between two videos on a mesh?

Hi there folks,

I am struggleing since two days now with the new Media Framework.
I want to switch between two or more videos.
Everything works fine except of the seek note of the media player. Somehow it skips this note. I have set up a new scene just to test if the seek note is working at all. Somehow it works sometimes, sometimes it does’t.
Are there limitations how to use it? Do both of the media player videos need to have the same replay length?
Does the seek note only work, when the video is displayed?

I hope someone out there could help me here :confused:
