I have an LG - 43" Class LED HD Smart webOS TV (Model 43UM6910PUA).
I keep all my videos stored on an external hard drive. When I connect this drive, a SEAGATE Expansion Portable 2TB External Hard Drive HDD (Model STEA2000400), to the USB port (back, side) and go to thumbnail view all I see are generic folders with the titles I have given to them. I do not see any of the "folder.jpg" poster/cover art images which I have in included in every folder together with the video(s) themselves. Why are these folder.jpg images not showing up in thumbnail view? I have no problem
