Why does the region code error when burning a disc?

Question

DVD

Good day to all. Using Burning Studio or CDBurnerXP, I uploaded a folder (video) to the video_ts disk. When viewing from a computer, everything is fine, but when through the disk, namely, autorun, it gives an error, saying that the region code is incorrect. Why is that? As soon as he didn't try. Through the Task Manager, changing the code to 5 does not help either.
