When they are not in order it looks like:

A:91864.773438 V:91864.751222 A-V:  0.019 ct: -2.925 856/856 
A:91864.804688 V:91864.911222 A-V: -0.103 ct: -2.929 857/857 
A:91864.851562 V:91864.831222 A-V:  0.021 ct: -2.927 858/858 
A:91864.890625 V:91864.871222 A-V:  0.019 ct: -2.925 859/859 
A:91864.929688 V:91865.031222 A-V: -0.103 ct: -2.929 860/860 
A:91864.968750 V:91864.951222 A-V:  0.021 ct: -2.927 861/861 

mplayer all the time thinks a-v is out of sync and corrects all the time.
In reality the video frames are in correct order but have incorrect pts values.
