Strange DVD832 1 has USB interface, but it can't play video, only MP3 music. How can I play the video normally?

My strange DVD is an enhanced version of 8000. The problem is the same as yours. It can only play MP3, but strangely, it can play video. I released the Chen Wenjing Square Dance in Wuhan with a USB flash drive. Ask the customer service what's going on Customer service insists that only MP3 can be played, and there is no video function. Then you can put a square dance video, and the customer service is speechless.
