Forumbox has mentioned some multiplex moves and switching to MPEG4.
I've had a quick look on Digitalbitrate and can confirm this.
The channels mentioned are as follows:
Colors Cineplex
COLORS
alibi +1
Dave ja vu
GOLD +1
Home +1
Sky Premiere +1hr
TCM +1
Sky Crime +1
Moves often mean you will need to re-add any of these to your Favourites if they were previously on your Favourites.
