Watching Spiderman on Sky Movies was terrible this afternoon. Freezing every few minutes. OSCAM not reporting any errors, but curiously if I switched to MGCAMD and looked at the log files I see the following just as the video freezes:-

and at this point in the log file the video stops freezing and returns to normal.

The entries stating "[mg0] WARNING, both cws changed !" tie in exactly when the video freezes. I have tested this theory several times this afternoon and a video freeze is always accompanied with the "cws changed" warning message. So the question is what are these warnings and why are they clearly upsetting MGCAMD and OSCAM and CCAM?
