When both are played in VLC player the AVI-Mux GUI mux is correctly displayed but the VirtualDubMod mux is incorrectly displayed

I don't know for sure but doesnt VLC player access and detect AR signalling at stream level?

Can you confirm whether the aspect ratio signallng information of MKV files is stored at the container level or at the stream level. And what level should software media players be looking for?

MKV stores aspect ratio in the container, and it should stay there. However, the bitstream can contain ARS; mmg will detect and remove it in that case (will push it to the container level). Could be that VDub doesn't do that, while VLC never checks the bitstream for AR.

So it's quite possible for double decoding to happen, or container-level when only bitstream-level AR is present, which is why I always use mmg. =p
