thanks for the help from twonky-christian. He made the required changes in the TwonkyMedia code that i was able to port my player extension to the new web interface.
Here is the list of changes in compare to the latest MediaBrowser version :
- Code Optimisation
- Removed leftover code from the MediaBrowser.js
- updated to JW MP3 PLAYER 3.99
Here is a screenshot (It still look the same


You can download the new version here: JW MP3 Player for TwonkyMedia 4.4.1
As stated in the title you need to have TwonkyMedia V4.4.1 .
To access the new version you need to go to http://x.x.x.x:9000/webbrowse-js instead of http://x.x.x.x:9000/webbrowse after installing the add on !!
I hope you enjoy it
