This video shows pretty well how to play videos from smart cards or usb devices on your Panasonic Smart TV:
It’s pretty simple: just connect your device, go to the media player app and select the Videos menu. This will list all the videos on your device. Just press play and you’re good to go.
But we tried these exact steps and it didn’t quite work.
When we connected the usb device, there was a message “USB device detected” but the second message showed the error “No device inserted”.
The problem is that the file system of your usb flashdrive needs to be fat32, otherwise it will ignore the usb device. So format your usb device with fat32, copy the video again on your usb device and you’re good to go. 😉
