While the PC speed may affect the smoothness of the waterfall, I am rather
dubious that it can impact the quality of the captured images.
I would tend to point the finger on the video card used, or on the resolution
settings. Spectran works best at 24 bits-per-pixel (16,777,216 colours or 'True 
Color'
in Windows parlance) or at 16 bpp (that's 262,144 colours, or 'High Color').
Working at 8 bpp is 'tolerated', but the results are less than spectacular...

Just to add some clarification, I have no interest in the quality of the local 
display,
just the quality of the captured image. My plan is to sit this in the corner 
listening
to MB7LF on a dedicated receiver and dumping the output to a web site every
few minutes. Anyone have any thought about how frequently this needs to be?

How does the system work, is the captured image derived by screen capture
or from internal data?
