Recording high quality video using a local buffer with FMS 3.5

Hello, I'm currently working on a webcam recorder to record high quality video. I had the recorder working before, but the video quality was quite poor. Instead I'm trying to use a client side buffer and then upload the buffer after recording has stopped. I thought after I unattached the video and audio from the NetStream that either a NetStream.Buffer.Empty or NetStream.Record.Stop event would be sent when the buffer was finished uploading. What is actually happening after I start recording is two NetStream.Record.Stop events are being sent in a row, so recording never really happens. Also, on the server side I'm trying to save a user name and password into a variable, but I'm not sure how to go about doing that since the application script is just a bunch of callback functions. I hope someone has done something similar so they might be able to help...
