As shown in the picture: Your insertion should be a video.

Use a converter to convert the format of your video. We recommend WMA. Remember to use the default format for conversion

If you are converting audio to WMV, it is embedded by default

Generally, this is the case. Format issues or if you install a player that supports a comprehensive range of formats, your computer will be fine. If other computers do not have a playback environment that supports this format, they will not be able to play it (you can also use a decoder that is supported by WIN).
