Thank you very much. Actually i dont know what it takes to make it compatible to Maemo 4. If someone directs me to some useful hints i will look into it.
One question. Does the original necroplayer works on maemo4? I noticed the original author of this player (CtHx Ъ) made an update very recently (added some playlist-handling and +?), so he is still developing it. Maybe he has some ideas.

btw, everyone interested in the sourcecode, pm me. not posting it atm as it needs a major cleanup
