You can use this tool to generate play lists for the TMP 200 HD

Enter the file names of the media you have on the USB stick (without slashes) as well as the optional Display Time (images only!). Make sure the generated file is saved as: play.lst. Please select 'All files' under the 'Save As...' option when prompted to save the file.
All media files included in the play list must be copied, along with play.lst, to the USB drive.
