I am having a similar issue .. Once recording a video, the video will play back within the NCH Debut package itself, but if I try to play it back in Windows Media Player, the audio plays, but the video is completely black. I wonder if it is a codec issue .. if I put the recorded .mp4 file into an editing package or play it back in VLC Media Player, then the audio and video both play fine. So does Debut use some unusual video codec in its .mp4 output files I wonder ? Why should some media players display the Debut output file fine, while others play back the audio only with a black screen ?
