RPS's Command Line Entry window allows you to play bookmarks from any kind of catalog file.  Just maintain the correct format of the playback link, then copy it directly from Word, Excel, or any other application, to your clipboard.  Then, press the 'paste command line' and 'play command line' buttons, or the u and i keys.  Your bookmark will play in RPS's Video Playback Window. The Command Line Entry window doesn't even need to be open to use this feature!
