I've searched here for an hour with no luck, so here goes:
I use Winamp to load podcasts onto the E280 in their folders into a folder named PODCASTS. Then I use Winamp to create a playlist from those files, (I then randomize it but edit certain shows to play in order), and save it in the PLAYLISTS folder. When I try to play the list it says LOADING then I get an error that flashes by so fast I can't read it and get thrown back to the playlist menu. When I play that playlist in Winamp is works fine, playing the files from the Sansa. Is there something basic I'm missing about this?
Below is the beginning of the file, it seems right to me, but I always use a player program to make m3u's, not a text editor.
