I cant understand Tata Sky's logic. They provide some downscaled HD channels in proper 16:9 aspect ratio such as Comedy Central, Nat Geo Music, Nat Geo People, Baby TV, etc. On the other hand they provide other downscaled HD channels in 4:3 aspect ratio such as History TV18, VH1, Travel XP, etc.
Why dont they follow a single rule? Either show all downscaled HD channels in 16:9 aspect ratio or show them in 4:3 aspect ratio.
