Changing Video when its been divided into chapters.

Question

I have a media control on my .aspx page and it plays a video. The video has a lot of chapters. When I try to play next video on click of a buton it gives a error

 

When implementing a derived StateManagedCollection, the implementation of CreateKnownType() must match the implementation of GetKnownTypes(). 

 

If I don't include chapters in the video then it plays different videos without any error. Whats the reason behind this. Can anyone tell.
