Hello, I just bought a Sandisk usb flash drive. I copied a video file from my computer onto the usb and then tried to play it on my dvd player. When the screen came on, it recognized my usb but the file was nowhere to be found. On the computer it shows up though. So I followed an online suggestion to reformat my usb so my dvd player can locate the video file. However, I made matters worse..now my dvd player does not support my usb at all. Also, the red Sandisk icon on my computer is gone! All I see when I plug in my flash drive in my computer is "Removable disk (F)". How can I fix this and be able to play the video on my dvd player??
