Thanks for posting about it. It was approx. 2 days ago. I noticed it but forgot to post about it.
Regarding changing the aspect ratio, its done to broadcast the channel properly on old CRT TVs. But IMO all DTH companies should broadcast these kind of downscaled HD channels in 16:9 aspect ratio so that they look proper in LCD/LED TVs. At least Tata Sky should do this as they claim themselves to be a premium DTH company.
