Took a while, but finally I pushed the development version for the N900 to extras-testing. The noticeable changes compared to the current stable version 0.10.5 are:

* Many smilText and expressions for SMIL state improvements
* Fix playing files in directories containing utf8 characters
* -max option for knpplayer that uses the full screen area
* Add pseudo process that first tries gstreamer and then mplayer

B.t.w. for harmattan the porting efforts can be found at https://garage.maemo.org/frs/?group_id=42 and WorldTV at https://garage.maemo.org/frs/?group_id=753
