Storytellers - Screen Recording

I am recording a Podcast with headset and microphone.  When I interview a guest I also want to record the video recording. I tried "Screen Recorder for Google Chorme" and "Nimbus Screen Video Recorder," but both only records the video with my guests' voice, but not mine.  

I have posed this question previously, but no one seems to have an answer.  Can you please point me in the right direction or offer me compatible software that will allow me to record the podcast video with sound?

Thank you!
