The videos I import in seemusic dissapear. I tried a lot of formats and resolutions without any result. It only plays the adio.

Ok - in that case, the issue is likely with the specific video file.

- After you import the video file and assign it to a piece, click Video Settings in the Media Settings window. Try moving the video up using the Position Up Down control - there's a chance it may just be low on the screen if there is black at the top.

- If that doesn't work, please send a download link to the video file, so that I can test importing it over here.
