If you can do that at all the information on how the usb has to be formatted and what files will work will be the owners manual for the specific model of JVC TV. Some TVs only use USB for updates.
Is it a smart tv? If so, simply format the USB at the windows default, I think it's fat32 or NTFS, I can't remember Bang a vid on to it, and start the integrated player. That should do it.
If it's not a smart tv, you need some sort of player to watch the movies. That can be by a DVD/player (if it has the functions) or an Android Box or equivalent that connected to your TV by HDMI or whatever.
