you first need to rename the mpeg file to M4V00001.MP4 where the five numbers can be anything, so just" M4V(five numbers).MP4"
then put this file in a folder named "100MNV01" on the root of the memory stick,

for future notice
google is alot faster than waiting for someone else to use up there own time
be glad im so kind

Thanks alot.. worked fine..
