Dialogue not heard on direct casting

I have come across a few MP4 files which replay perfectly locally but when casted directly to my TV on EZCAST, lose the dialogue band. There is still music output but instead of dialogue there is just a crackling sound.

Can someone explain to me why is that and is there a way round this problem? For example would converting the MP4 format to say AVI, could correct the problem and what specific precautions do I need to take?
