Can you please compare the tatsky HD with Kerala vision cable tv STB HD . I am only comparing malayalam channels.Which one will provide better clarity.Is there any problem to handle the Malayalam channel numbers start with 18XX. The Kerala vision Malayalam channel numbers start with 1. I am planning to move from Sun direct.I am looking for a STB which my family can handle and change channels very easily. I have not seen tatasky and Kerala Vision. Waiting for your suggestions to finalyse
