I got a call from Tata Sky for an upgrade to the new PVR based STB at Rs 5999/- for existing customers. My delivery should happen with the next 2-4 business days. According to http://broadbandforum.in/tata-sky-dth-service/36376-tata-sky-dth-service-hdmi-output/, there is no HDMI output – only SPDIF and component. Technically, I should be able to get HD over component (the STB is MPEG4 capable) if and when Tata Sky starts providing HD content. The Dolby Digital streams will be taken care of by the SPDIF interface.
I did dabble with Comcasts PVR stuff when I was visiting US earlier this month. The ability to pause programming is just too sweet. My hopes are high for Tata Sky+ service.
The DVR has component and TOSLINK output. The picture quality is much better. The PVR works decent too. Its not the most impressive device out there but I suppose it will do for now.
