Comment (by J.Pilk@…):

 I'm away from home with access to a poorer signal, and see much more of
 stuff like this:

 which I think shows (mostly) single packets being dropped and on video
 does cause mild pixelation - random rectangles appearing briefly.  Partly
 I suspect the usb device and its driver, but the best cure is a good
 aerial.  And maybe moving away from taxis, pizza shops, police stations.

 As I said earlier, this ought to be on the user list, where you might get
 wider range of expertise.
