Hello M.Rajkumar, thx for the reply and help,
the problem is not to play and see the video's, that works very well,
all the files in components\com_hdflvplayer has wite permission exept the map video's, is not possible, i get:
"Unable to set file permissions
Details, Unable to chmod /domains/fonsamoris.nl/public_html/components/com_hdflvplayer/videos to 755"
if you go to: www.fonsamoris.nl /mainmenu/video's, you can see the warning your self, I don't know what to do with the warnings,
