No. Ist's not interfering with Hybrid.
Ist's triggered by one of the settings in MPC HC, or ffdshow. This dies not happem here and I'm pretty sure that there is no additional audio track added by Hybrid.
-> this looks to me like something triggered by some setting in your setup during playback.

OK, well interesting, I will take a look around, and see if I can figure out why it is saying that, and I can also test with VLC, or other programs. Although, I notice if I save it as an .mkv, in the exact same fashion, it does not show up in MPC-HC. I wonder if it is something to do with the .mp4 container itself?
