If it gives playlist as a menu option, how comes there's no information on how to create one? I've Googled and can't actually find a solution
well. it is not that hard. and actually it is done with the same method as you are doing with your mp3 files using let me say winamp. just select your files form the disk and save them as a play list. the point is you may have to edit file directory references in the playlist file regarding the directory structure of your disk.
The easiest way would be to create a folder with all the music videos in and press ok on the first one and set repeat all.
It should be possible creating playlists, just make one in your favorite movie player on your computer and save it with relative paths, like
\video\music\artist\song.avi
\video\music\artist\song1.avi
\video\music\artist\song3.avi
.
.
.
so it shouldn’t be something like:
C:\Document and Settings\My Documents\Downloads\video\music\artist\song.avi
if u use the full path the WDTV won’t find it.
