Navigating between MP3 player and FLV player on simulated Web site

[FONT=Arial][SIZE=3]I went through the Adobe Classroom in a Book for AS 3. I now have an MP3 player from the tutorials and I created a separate FLV player from that. Both players link to external XML data files to get the song and movie info. I’m trying to create a local, simulated Web site (all files on a single computer) for a class project that can navigate back and forth between to two players. I have main navigation buttons on this simulated Web site to call each player. What would be the best method to implement going back and forth between the players seamlessly–gotoAndPlay’s on the same timeline, loading external SWFs into a blank MovieClip on stage, or something totally different?
Thank you for any help.
