I’ve uploaded a new version of wordTube to wordpress.org. This version contain the new JW Media Player V5.1. The path to the player is now editable, so that you can upload your custom version (You can also use version 4.x, as the player is backward compatible). Please note : In the next version I will remove the flash file from the repository. If you not move your flash player file outside the plugin folder, it will automatic erased during the upgrade routine.
Please verify the path of your player in the wordTube options, if you have any other trouble with the new version, please report it at the forums. Thanks !
