Why does the official website advertise than Xiaomi TV can support a certain video format, but it does not actually support it?

Solution:

Please support genuine film and television resources! Some video formats are not supported mainly due to copyright issues. For example, when using a TV to play MP4 format videos in a USB flash drive, some can be played, and some direct display formats are not supported. This is because although the same is MP4, there may be differences in the video encoding format, so there will be actual Unsupported circumstances.
