Marcus,
Here is the stack crawl.

Can't register system time source

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.
Cheers
David
