FMOD Unity Sync Issue

Hello, I have written a script for Unity and I can’t manage to get it to work the way I want - the video player video set with DSP Time work exactly the way I want, but the video player videos with the other time set than DSP time have issues - they are lagging, looping, and the videos that are meant to loop just don’t. Could you please help me out? It’s my first time using FMOD and I’m completely new to it. The script is here: https://drive.google.com/file/d/1APtkAo76cRx7Q_cj8Ma__E6f2qQF1uhO/view?usp=sharing
