Flash Video Jukebox - Sound Stops After 45 Minutes

I made a flash video jukebox, so it reads a dynamic playlist of F4V files for hours. Everything works well but after about 45 min the sound stops and after 2 hours the flash player plug in crashes. It seems like the cache is not accepting more F4V videos and then crashes. If I auto-refresh the browser every 2 hours it works but I would like to avoid having to refresh the browser and just clear the flash player cache if that's where the F4V go? I can't find any info about where the F4V files go when you play them!

Frame 1 gives the variable vidReference the value of the video file name:
VidReference = trackToPlay;
Frame 2 does the playing:
var nc:NetConnection = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
nc.connect(null);
[Code] .....

This is the function that detects when video is done playing, still on frame 2:
function netStatusHandler(event:NetStatusEvent):void {
switch (event.info.code) {
case "NetStream.Play.StreamNotFound": newTrack();
break;
case "NetStream.Play.Stop": newTrack();
break;
}}

And the function newTrack() is just giving the variable trackToPlay a value (the file name of the next video). And then says to gotoAndPlay frame 1, so it kind of reinitializing the player. The objects are re declared in frame 2, is that the problem here?
