That has something to do with it but:

Maybe it is. Come to think of it the derivitive sources of the cable are digital on some stations and analogue on others (i.e., some go through more satallite/router interations that others). Since the LED is an analogue device (i.e., it can be partly on/dimmed) there should be more jiggling on stations that have a more analogue (read slower and gradual vs digital refresh) basis. (and I'm showing my age, some/most LED's now are digital aren't they?!?) I checked this this AM and that's what happens off the DTV receiver. More jiggling occurs on stations like Nickelodian which are running analogue (never been digitized) material. Black and white seems to jiggle more than color but that could be as much the type of processing that goes into the programming as anything relative to the perceiver. I still don't have a really good feeling that any of this is more than a post hoc explanation though.
