When I playback the recorded movie clip, the audio and video are not well synchronized. Why?

There are some situations that will result the follwing situations:

1. If the video clip in the recording end is well synchronized. It's perhaps due to the weak computing power of the receiving end or that the Direct Draw is not installed properly.
2. If the recording end is equipped with a printer port camera (with less transmission bandwidth) or the computing power is not enough, please low down the recording frame rate.

You can adjust the value according to the following table. Or you can get the suitable frame rate by way of "Frame Rate Auto-Detection" mechanism.
