(That is probably a bad idea, but unrelated.)

Sorry, I am not sure I understand:
Did changing -intra_vlc 0 to -intra_vlc 1 and 
-non_linear_quant 0 to -non_linear_quant 1 help or not?

And could you clarify if I can reproduce the issue (that 
the file is not correct) only with Mediainfo or is 
there another possibility?
