Circuit keeps changing for about 4 times after manually requesting a circuit change. Result: Can't view videos from sites that are censored in many countries

Title. When I try to watch a video on a site that's blocked in many countries, I manually change the circuit until it the video loads. But the circuits keep changing so the video can't be played unless you're very lucky.

How to reproduce: Establish a new circuit when viewing a website (to see that it keeps changing by itself for about 4 times). If you need it, I can tell you the website which is most affevted by it from my user experience. But I'm quite sure it's caused by the unwanted auto-changing.
