Mine is always on, Reverend seems to have his always on too.Is the CPL generally used all the time, or do you take it off during different conditions?
If you remove it at night then you should reduce the amount of motion blur by about 50% but I've never noticed a difference, if I take it off then I tend to forget to put it back on and during daylight it makes a huge difference to the image quality so I just leave it on.
The advantage is that it removes the light reflected off the dashboard which would otherwise destroy the contrast and colours, also the reflections don't move while the outside view does so each pixel is both moving and static which makes it difficult for the mpeg encoder to encode the movement and given limited bitrate that looses detail and image sharpness.
