My Parents daily and me-bro only at weekend(sat-sun) enjoy viewing on Sony Bravia LCD which was purchased on 2011 cric world cup with Videocond2h HD DVR-4611.
we have another multiconnection there of d2h HD STB2011 running on "Match ON Videocon Flat TV" purchased on 2003 world cup.Infact, we realize these TV's don't require HD content as SD contents looks awesome only need DD there.still u love hd on it.
till now it is running in good condition and now I think we'll upgrade or buy new purchase may be in next1-1-1.5yr of 4K tv only there.[Although I seen there internal structure of so called "Flat" Picture tube once in past...it was somehow adjusted

there current LED-LCD quality might be good so as economical]
Brother also using Bravia LCD in "another" city . (offourse with d2h HD STB2011)
So both Bravia LCDs are running extremely fine, no probs till now.
As I mentioned earlier, I make use of Dell-AIO LED THX certified with d2hHD STB in "another" city.
So now eagerly waiting for "Videocon d2h 4K UHD DVR-STB", so can upgrade all existing HD STB one by one.[Burden on Pocket

but 4K Future Ready Factor will regulate it atleast for next so many years

Will keep d2h HD DVR4611 model as it is, atleast for next few years.
