Dot crawl is little dots that are visible in the picture. They really stand out in the reds. If you look at this
link , you can see an example. Look closely at the planet in the top picture and you can see the dots all through it. It is caused by the comb filter in my Pioneer CLD-703 not being as good as the one in my ADVC-100 capture device. When I did some test captures using composite, there was no dot crawl.
