Marcus, Here is the stack crawl. loading symbols Can't register system time source _debugger: _debugger: +0007 ec084853: * c3 retn media_addon_server:sc frame retaddr fd001604 80005741 MediaAddonServer::ReadyToRun(void) + 00000099 fd0016ac ec15feab BApplication::DispatchMessage(BMessage *, BHandler *) + 000001cf fd0018cc ec168c49 BLooper::task_looper(void) + 0000029d fd001b58 ec1620ec BApplication::Run(void) + 0000005c fd001b6c 800074c1 main + 0000006d fd001b84 800050b5 _start + 00000061 The error is from this code BMediaNode *ts = new SystemTimeSource; status_t result = mediaroster->RegisterNode(ts); if (result != B_OK) debugger("Can't register system time source"); But I think this is not really the problem. I removed the code to launch the media_addon_server from the media_server and did it manually and there was no problem running the media_addon_server. I then changed the code to launch the media_addon_server from using the mime type to using the directory again. This also works fine. So I think the problem above is just that the launching with mime type is not working on my machine. Now everything runs but I don't get any sound. Looking at the Media prefs I have no output control to assign to the sound card (I have an input control though). Anyway, this is enough for me to debug my mov reader so I can work with that. Any thoughts on the no sound issue? cc'ing to the mailing list in case anyone is listening.
