Matroska Muxer & Graphedit: No time stamp...

[defaulk9]

I'm having trouble with muxing video streams from several matroska videos into one using Matroska Muxer. My Graphedit setup:

Vid1.mkv -> Matroska Muxer -> File Writer (muxed.mkv)
Vid2.mkv -> Matroska Muxer
Vid3.mkv -> Matroska Muxer

The error message I get is this:
The graph could not change state.

No time stamp has been set for this sample. (Return code: 0x80040249)

What am I doing wrong?

You'd better use mkvmerge for that. Does the Matroska Muxer have more than one input pin (the one from Haali) ?

Thanks for your response.

Does the Matroska Muxer have more than one input pin (the one from Haali) ?Yes, the pins hook up just fine.

You'd better use mkvmerge for that.It's just that I've read several other places that you should be able to mux using Matrsoska Muxer in this way. But you can't?
