Audio Problems When Editing

[yoieyo]

Hi,
I currently use DXTory to record my games. When I go to edit them, I can only hear in-game sound, not my voiceover. Is there a way to change it to 1 audio channel? If this is not available, can you please list the current video editing softwares that have the ability to edit DxTory Videos.
Thank you for reading my post, I hope anyone can reply and answer my question ASAP.
