The screen stays black and I can't see the video

This problem is usually caused by the lack of powerful codecs in your machine. You could try this:

1. Download and install the K-Lite Codec Pack Basic
2. Run “Codec Tweaker” application
3. Go to “Preferred decoders” and change “H.264″ from “Microsoft” to “LAV Video”

If you continue having problems, try this:

1. Uninstall K-Lite Codec Pack Basic
2. Download and install LAV Filters
3. Download and install Win7DSFilterTweaker
4. Run “Codec Tweaker” application
5. Go to “Preferred decoders” and change “H.264″ from “Microsoft” to “LAV Video”
