Many times you will see playlists with a US, UK, CA or similar in front of every channel or something after every channel and don't have a need or a want for this. These can be removed and make your channel guide look much cleaner.
To remove prefixes and suffices from the channels in your channel guide; go to Settings/Appearance/TV Guide, then click on Channel Name Editor, turn it on then add the prefixes or suffixes you want removed, I'm sure you will like the appearance of your channel guide a lot more.
