Replay didn't record remote webcam

[Rooftops]

I just spent an hour and a half in a skype call that I wanted the audio and video recorded from, and replay didn't record any of the video. Replay was open before I opened Skype, and the audio recorded fine. It also said there were two video streams. Could it be the switched file type? I'm a little bit annoyed that it didn't record.

Edit edit: It didn't actually record anything, the blackness was just the player background.
