In the example when mxf is created, has 12 channels and the mxf created is corrupted, is possible to play but has wrong video and audio timing.
All the file I sent are true native lxf version 1, you can use to test with trust.

Note: The files from http://titan.codemill.se/~tomhar/samples/lxf/ not all are lxf version 1 native
1.lxf
100723-TAM VAN HOA-00240.lxf
F0015132.lxf
PM4617.lxf
ZB09_108_LXF_V1.lxf
F0000721.lxf
F0015132.lxf
LXF_File_1.lxf
All of them have invalid format when used in VR, 2 channels are not use in native lxf version 1.

Last Mediainfo reports badly 12 chanels too with device and trace, although find the 16 PCM channels inside in basic mode.

Is this also reproducible with current git head?
Please add complete, uncut ffmpeg console output.

I tested the patch and works fine with "ffmpeg -i input.lxf -vcodec copy -acodec copy output.mxf", the files created have 4,8 or 16 channels and they can be played well.
Please let me now if you need something else.
Thank you
