Hi Ulrich,

Thank you for you input. What I probably would have said in my message
and didn't was in receiving video it is just as slow on my P166 as my
486 :)

Nothing has changed in that respect.

In this case, neither your computer nor your connect speed are the
bottle neck, but the quickcam. The lower the light that illuminates
your scene, the longer it takes to accumulate enough charge on the
CCD - elements to form an image. This is independent of your CPU
performance. At low light levels, it can take several seconds per
frame.

Try to crank up your light, and you will see a difference.
