any naming convention listed here http://wiki.wdlxtv.com/How_to_use_Movie_sheets_v2 should work
I used the linksheets.pl script which I did not write, the only edit was to disable the blinking led
as led control is different on newer devices
you still did not mention how you named your theme folder?
also could it be all the special characters you have in your file names ?
