Sometimes a recorded live streams/webcams video and audio may also be out of sync because the server is sending incorrect timestamps

1. Click Tools -> Fix FLV and select the file to be fixed.
   Or, if the file is still in Replay Media Catcher's main list, right-click on it and select Fix FLV.
2. Expand the File Contents section
   
   
   
3. Set timestamp to 15 and click "Fix Time".

If the resulting file is still fast or slow then the time stamp can be adjusted further. But, 15 usually does the trick. Be sure to click the Fix Time button, or your changes will not be applied.
