I need to multiplex an IMA ADPCM audio track into a WMV file for a personal video player.

I've dome searches on here, google etc, and tried WME 7 and 9, adobe premiere etc, all to no avail.

I tried Windows Stream Editor, but that only multiplexes WMA into WMV :o

Does anyone have any suggestions ?
Thanks in advance

Cant see how you can multiplex with VLC, only transcode - and that doesn't give options for IMA ADPCM.

The only video files the player supports (it's a mustek PVR-H140) is ISO Mpeg-4 video v1 with 24khz 96kbps 4bit IMA ADPCM sound.

I have the sound extracted & converted as a wav and a .wmv video file, I just need to remux (though "just" seems to be almost impossible :o )

if you put the WMV stream and audio stream in an AVI together first you can then remux to asf with VLC.

VLC encodes the wmv but without any sound - guess I'll have to keep on looking :(
