For channel icons, it depends on the device. For Beyonwiz T and U series PVRs, I manage the channel icons, and communicate about it in the
Request for updates for channel picons topic on the Beyonwiz forum.
The Beyonwiz channel icon for Sky News on WIN is available in recent public betas, and the channel icon for Your Money has been submitted to the icon repository, but hasn't yet been merged in or distributed. I'm aware that a rename of the Food Network on SBS, with an accompanying new icon, is due in November and that will be made available in the same way.
