Flash视频播放器内存问题(Flash Video player memory issue)

 我用播放列表制作了一个视频播放器。 大约45分钟后声音停止！ 视频继续播放。 我播放短片（每个约3到4分钟）。 
 
 播放器基于2帧： 
 
 第1帧使用文件名定义变量VidReference： 
 
VidReference = trackToPlay;
 
 第2帧播放视频： 
 
var nc:NetConnection = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
nc.connect(null);
var ns:NetStream = new NetStream(nc);
ns.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
const buffer_time:Number = 2;
ns.bufferTime = buffer_time;
ns.client = this;
ns.play(VidReference);
var vid:Video = new Video();
vid.attachNetStream(ns);
addChild(vid);
vid_frame.addChild(vid);
 
 一旦视频完成播放，它将进入第1帧（将新值放入VidReference变量）并返回第2帧以播放新视频。 我是否应该在每次加载新视频时删除视频对象？ 我每次循环（第1帧>第2帧）并将每个视频添加到RAM中时，我是否实际声明了一个新的视频对象，最终压倒了Flash播放器？ 
 
 我听说过垃圾收集，但我不知道如何删除视频对象，以便从内存中清除它（以及视频本身）。 
 
 当我检查System.totalMemory它每次加载新视频时都会加起来，我无法弄清楚如何从内存中删除旧视频。 

I made a video player with a playlist. After around 45 min the sound stops! The video continues playing. I play short clips (about 3 to 4 min each).
 
The player is based on 2 frames:
 
Frame 1 defines the variable VidReference with the filename:
 
VidReference = trackToPlay;
 
Frame 2 plays the video:
 
var nc:NetConnection = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
nc.connect(null);
var ns:NetStream = new NetStream(nc);
ns.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
const buffer_time:Number = 2;
ns.bufferTime = buffer_time;
ns.client = this;
ns.play(VidReference);
var vid:Video = new Video();
vid.attachNetStream(ns);
addChild(vid);
vid_frame.addChild(vid);
 
Once the video is done playing it goes to Frame 1 (to put the new value to the VidReference variable) and goes back to frame 2 to play the new video. Am I supposed to delete the video object each time it loads a new video? Am I actually declaring a new video object each time I'm looping (frame 1 > 2) and adding each video to the RAM, and in the end overwhelming the flash player?
 
I've heard about garbage collecting but I wouldn't know how to delete the video object so it is cleared (and the video itself too) from the memory.
 
When I check System.totalMemory it's adding up each time a new video is loaded, I can't figure out how to delete old videos from the memory.
