a host server for connecting with a plurality of browser clients;

a web site having an embedded code that allows a connection between said host server and each of said plurality of browser clients;

a media server for receiving first live video and audio data from a first individual browser client and second live video and audio data from a second individual browser client;

wherein said host server receives instructions from individual browser clients requesting said first and second live video and audio data and said host server requests said media server to rout said live video and audio data to each individual browser client that requests said live video and audio data;

wherein said media server connects with said individual browser client that requests said first and second live video and audio data and streams said first and second live video and audio data to said individual browser client that requests said first and second live video and audio data; and

a customized flash video player in each of said plurality of browser clients for receiving said first and second live video and audio data, wherein said first and second live video and audio data are continuously synchronized by said customized flash video player.

2. The network of claim 1 wherein said media server divides said first live video and audio data into a first set of video and audio frames and said second live video and audio data into a second set of video and audio frames, said media server marking each of the first set of video and audio frames with a first time stamp and each of the second set of video and audio frames with a second time stamp;

and wherein said customized flash video player continuously synchronizes said first and second live video and audio streams by measuring a time difference between said first timestamp and said second timestamp at set intervals; and

wherein said customized flash video player slows a stream rate of said second live video and audio stream if the time difference exceeds a predetermined amount of time.

4. The network system of claim 1 wherein said media server further comprises a memory for storing said live video and audio data, wherein said media server stores said live video and audio data in said memory and said browser clients receive said streamed video and audio data from said memory.

5. The network system of claim 1 wherein said browser client further comprises a video module and an audio module for transmitting said live video and audio data to said media server.

6. The network system of claim 1 wherein said host server further receives message data from at least one browser client, the message data routed to said individual browser client that requests said live video and audio data.

7. A network system for providing live video based discussion to a content delivery network comprising:

a host server for connecting with a plurality of browser clients and with a content delivery network;

a web site having an embedded code that allows a connection between said host server and each of said plurality of browser clients;

a data server connected to said host server, said data server receiving message data from said plurality of browser clients;

a media server connected to said host server, the media server receiving live video and audio data from at least one of said plurality of browser clients; and

wherein said host server receives said live video and audio data from said media server and said message data from said data server, said host server streaming said live video and audio data and said message data to said content delivery network.

8. A network system for providing live video based discussion comprising:

a host server for connecting with a plurality of browser clients;

a web site having an embedded code that allows a connection between said host server and each of said plurality of browser clients;

a media server for receiving first live video and audio data and second live video and audio data from individual browser clients, said media server having a memory;

said media server storing said first and second live video and audio data in said memory as first and second stored video and audio data;

wherein said host server receives instructions from individual browser clients requesting said first and second stored video and audio data and said host server requests said media server to rout said first and second stored video and audio data to each individual browser client that requests said first and second stored video and audio data;

wherein said media server connects with said individual browser client that requests said video and audio data and streams said first and second stored video and audio data to said individual browser client that requests said stored video and audio data;

a customized flash video player in each of the plurality of browser clients for receiving said streamed first and second video and audio data; and

wherein said streamed first and second video and audio data is continuously synchronized by said customized flash video player.

9. The network system of claim 8 wherein said host server receives a translation request for said stored video and audio data from a first browser client;

wherein said host server sends said translation request to said plurality of browser clients; and

wherein a second browser client adds a text file having caption segments comprising a timecode, caption text and a blank line to said stored video and audio data.

10. The network of claim 8 wherein said first recorded video data is divided into a first set of video and audio frames and said second recorded video data is divided into a second set of video and audio frames;

wherein said media server marks each of said first set of recorded video and audio frames with a first timestamp and each of said second set of recorded video and audio frames with a second timestamp;

said flash video player continuously synchronizes said recorded video and audio streams by measuring a time difference between said first timestamp and said second timestamp at set intervals and increasing a stream rate of said second live video and audio stream if the time difference exceeds a predetermined amount of time.

11. A method for providing live video based discussion via a network comprising:

providing a host server for connecting with a plurality of browser clients;

providing a web site having an embedded code that allows a connection between said host server and each of said plurality of browser clients;
