By the way, this is a bad idea:

video_speaker_name=char(dd.name);

It pads the CHAR matrix with spaces, if the names have different sizes. Use a cell arry instead:

video_speaker_name = {dd.name};

But the main problem is, that we do not have any chance to understand the cause of the problem based on the mnessage "Assertion failed". Please check the mentioned line 290 to find out, what has been asserted.
