Never. :no: Airtel and Dish TV have all LCNs arranged neatly by genre within each regional language. TS dumps them together. In Telugu, the order of the first few channels is Gemini Movies -> Sakshi -> Zee Telugu -> Gemini TV -> Gemini Comedy -> Gemini Music -> ETV -> ETV AP -> Star Maa. It is very haphazard.
Also, there are big gaps in the LCN arrangement. In English movies, for instance, 371-375 are blank but 376-385 are nearly fully packed. In music, 834-854 are blank and in sports, 467-470, 478-482 and 487-491 are blank.
