Nowadays, the TV is sometimes pitiful,
Some TVs support USB flash drive, but only support JPEG, GIF, picture format
You should pay attention to buy the kind of TV that supports playback of video when you buy a TV Oh.
If your TV doesn't support it, there's no need to change your TV. You can buy a DVD for a small amount of money, and then burn the square dance to a CD-ROM and watch it on your TV.
