Thank you guys for all your responses.
okay nambbus - firstly I am in no way, shape or form associated with any of the DTH providers, so there is no questions of trying to "defame" anyone here. I will praise a good service like crazy and go out of my way to promote it to everyone and similarly won't hesitate to slam the a** out of one that offers unsatisfactory performance or service.
I had been a TS HD customer since the time they launched it with 2 channels, Discovery and NGC HD and switched to D2H only because the former wasn't offering that many HD channels and I was paying nearly 500 per month for it and since I own an HD LED TV, I felt I should go for a provider that provides the most HD channels.
Last evening, after posting this thread, I sent off an email to the customer support, nodal desk and the CEO of D2H and slammed them for their poor quality picture. Within an hour, 2 guys from the technical department visited my place at around 9 PM and upgraded the STB with the latest software which I feel somehow took care of the color rendition and chromatic aberration issues and also the ghost like images were also somewhat improved. So unfortunately, I don't have pics from the previous condition to share with you guys here.
Now, after watching it for quite some time, I know my eyes have gotten used to it but I would still say that PQ wise TS HD is better, yes, even after the software upgrade on D2H, the difference doesn't look as stark as it did the first time I viewed it, but I have no hesitation to say that TS HD PQ was much better in terms of clarity & detail. I don't care much for the 5.1 audio output since I don't have a home theater installed, but the GUI of D2H is also way behind than what I saw on TS, it's laggy and not user friendly.
If and when TS launches more HD channels and offers a more VFM service, I might just go back to using it again but for now I will continue using D2H
Thanks!
