Memory Consumption on playing live streams

The problem that we encountered is that when we play live streams from flash media server , the flash player process in task manager start getting bigger .. so after 1/2 h .. it already reaches 2GB memory ... thats kind of frustrating. The live stream that comes to the client is composed on the server on many stream .. when one flv file is done ...another begin..when the last one is done..the first one begins , so the client sees a live endless stream . The application is here http://www.mycinemasite.com , its an online cinema. We need this problem solved asap , so if anyone can help it would be great.

Thanks in advance ,
Adrian
