Sky movies is pixelating all other channels work ok.

I can download and watch the movie but can't watch live. All other channels are perfect

I'd suggest fully rebooting the Sky Q main box.

Unplug from the wall for at least 30 seconds.  At this point, pull out and re-seat the HDMI caples at the Q Box and the TV.

Now plug back in the Sky Q box power and follow the on-screen instructions. This can take up to 5 minutes, and hopefully, you're back up and running, pixel-free.

Good luck.

Unfortunately it's still the same....
