I have a new Panasonic DMR-EX78EB dvd/hdd video recorder/player.
The manual says I should be able to play 'Divx' or 'avi' format video files from a usb memory stick. There was a usb memory stick with the unit with divx files on it which played ok.
If I copy avi files from my pc to a usb stick they will not play on the Panasonic. I get an error message 'format not known' or similar.
What am I doing wrong please
