You can see that I am using the plugin on my website so its working.
All I did was upload the two player files in uploads folder.
Upload all my videos in a folder using ftp in public_html
then go to wordtube and I see that it was no warning and had found the player here wp-content/uploads/player.swf
go in Media wordtube
Click on Playlist Preview edit
as I did not have play list I created one
than click on
add new media file
fill in title author description and than put a url in
URL to media file
my case /video/filename.flv
tick the playlist I want this file on right.
click Add Media file
When I done that I can see the video and repeat that for each videos I want in that play list
add the short code that is above the video in page.
