I always used to admire Tata Sky for using same exact name of the channel in its EPG as the name is shown on channel logo but since long time they are not perfect in this area.
Take an example of Nat Geo channel. Its HD channel's EPG name is in all CAPs "NATIONAL GEOGRAPHIC HD" but they changed SD channel name using small letters "National Geographic". Same case goes with Ten Sports channel HD and SD EPG.
Also they are using "HD World" title for TLC HD channel but they are not using the same for Discovery HD and AP HD although all 3 channels have HD World term in their logos.
There are many such small inconsistencies in lots of channels EPG names.
