In the XML Editor, click inside the hyperlink. Then click the tag hint bar (the small yellow rectangle below and at the beginning of the link).
Alternatively, at the top of the XML Editor, you can click the span bar representing the link. For example, hyperlink span bars have an "a" label, and cross-reference span bars have a "MadCap:xref" label. When you click on the link in the topic, the appropriate span bar at the top of the XML Editor will change color to indicate that it goes with the link. If your span bars are not turned on, click 
in the local toolbar of the XML Editor.
Select Preview Movie.
The movie opens in the appropriate viewer.
