I have generated several playlists from many, many songs loaded on a 4TB external hard drive. They play perfectly on the computer that was used to generate the playlists, but when I move the external HD to a different computer the playlist does not work. I have tried to "trick" the second computer by forcing it to have the same letter identification as the first computer but it still does not work. I am using the VLC media player default for playlists, xspf. Any suggestions? Thanks.
