deleting files off of usb port [View all]

Okay for some reason when I download a show from my computer and put it on a USB Stick, and Put the USB Stick into
my DVD player, three files show up, The tv show, but also "System Volume" and WPS Settings"

It wont allow me to play the show.



I put the USB Stick back into the computer and delete the show.

The computer says there is no file on the USB Stick, when I put the USB Stick back into the DVD player, its coming up
with "System Volume" and "WPS"

Howe do I delete these two files from the USB Stick where my computer is telling me there is no file on the stick.

Ive been using the same USB Stick for years and there has never been a issue.
