Editing a Recorded Meeting

So I have a meeting recorded and I would like to edit out a section that is irrelevant. I tried to use the integrated editing tool but when I cut out the section I don't want it doesn't actual cut it. Instead, when the video gets to that point it stops, loads up again, plays through the cut section very fast, and then continues on. I took a look at the offline version of the edited file and the problem persists. Does anyone know why this might be happening/how to get around it? I would like to make smooth cuts but I don't know if that's possible with a .flv.

Thanks...
