Don't use the format tool of the image!
Look here: http://www.hdmedia-universe.com/boar...hread.php?2013
In short words: Format your stick in ext2 (or ext3, but this is slower)
The ext2-partition on the stick has to be renamed to the label "RECORD"
You also need a "movie" folder on your partition.
After that HDMU should detect and mount your stick as HDD.
