When talking about resolution in the video world, the frame size (or 
resolution for most people) does not count for video quality nearly as much 
as bitrate does. What bit rate are you actually using at 640x480?  My 
settings for capture are 6000 for the lower end and 8000 for the high end and 
I do capture at 720x480.
