I still say that the quality of d2h HD is much better than TS HD.
All HD channels in TS judder (shaky screen movement whenever there is a movement of camera) it almost hurts your eyes. This never happens in d2H.
If you have d2H HD stb, you can compare yourself. There is nothing else to say.
And there is no USB recording on TS which d2H has from 2 years. Moreover, all d2H stb's (2222, 2244 etc) have both HDMI and Component outputs. TS has only HDMI output.
If d2H starts giving more HD channels soon, I would never switch to TataSky.
