Since my original article explaining how to get Windows Media Player to single-step a video, I've learned that there's an even easier way.
- Pause the video.
- To single-step forward, Ctrl+Click the Play button.
- To single-step backwrd, Ctrl+Shift+Click the Play button.
Backward-stepping is dependent upon the codec; some of them will go backward to the previous keyframe.
