An engineer came today again.......on first instance when we observed Star Gold HD, it didnt misbehave. Then after a while when he called up his senior to inform that issue seems to have vanished, i just changed to Star Plus HD. And while i was talking, it started to get out of sync. The senior told me to report again after 3-4 hours. And it was still the same. he has now said that he is forwarding my issue again. Lets see what turns out.I clearly see some patch coming on for DVR firmware......no other reason is visible.
