When you select a bookmark, CyberLink PowerDVD starts the playback from the bookmarked point and continues the playback of the disc/video from the point where it was bookmarked. To cycle through the bookmarked scenes, press the G key on the keyboard.

If the bookmarks are on a movie file, TV show, or video clip, you can just hover your mouse over the navigational slider to view the bookmarked scenes on it.

Hover your mouse over the bookmark to view a thumbnail of the scene, or click it to play the video from that bookmarked point.
