What world class Mr. Bishnu infact the New SD and HD STB's from Tata Sky and airtel are of very poor quality. Third class chinese hardware with poor picture and sound quality. Infact now in find Videocon d2h hardware to be lot better than airtel or tata sky SD and HD STB Hardware. In fact Videocon d2h hardware is good but their software is slow and needs revamp. My Videocon d2h stb went thru multiple high/low voltage fluctuations and survived plus Videocon d2h stb supports high symbol rate and search on the net, only good quality hardware can support hhigh symbol rate
Tata Sky is just famous for one thing- giving excuses for not having bandwidth like they have been doing since years and do nothing as they ave no intention to add bandwidth or new channels. Some people saying that Tata Sky has added 36 channels this years, i would just say that barring one or two all these channels are available on airtel or videocon d2h since ages
