Uploading movie component as a background

OS Win10
PsychoPy version 2023.2.3:
**Standard Standalone? y
What are you trying to achieve?:
I’m trying to upload a video 2 sec long which I want to play in a loop as a background during the whole trial. The trial consists of a series of audio files in random order.
What did you try to make it work?:
I created a loop with audio files, and I tried to add a video as a routine inside the loop, but then the video file is not played constantly, but appears on and off. I want it to be played constantly in the background, independanlty of other routines.
Thanks!
