Media Player works great now! I only test my converted movies and they play very very smooth without tearing. before the update, there was tearing and it was laging quite a lot. Now it plays as smooth as on my desktop PC!
Does anyone of you manage do install becomeroot!? I can't f****** find it in the application manager. The repository from maemo.org was added, already, but there is no becomeroot :-S
It was there, before...
