When AIMP is enabled, youtube videos are not included, why?

Question

YouTube

I don't know how it's connected at all, but when AIMP is running, youtube videos don't play. As I disable AIMP, everything works right away.
Why is this happening and how to fix it.

Answer 1

youtube via html5 or via flash player? Is the h264 codec installed and enabled in the browser? Does AIMP play video through directshow or in another way?
Well, the classic "update your video card drivers."
