yeah I might replace my all time favorite HD DVR-4611 with upcoming 4K UHD DVR...(Actually since last 1 months 4611 getting picture black out problem at power on every 4-5 seconds continue to next 3-4 minutes..then goes well .d2h service engg are unable to solve it.I expecting company d2h tech engg visit)Let's see how it goes as they ask only swapping

....
However, I'll still keep that DVR(with brilliant HW & Picture) as one of my connection..but prob is it requires 2 I/P signal wires.
No dates are cleared on 4K UHD DVR ...heard it's on way soon..
I'm expecting this 4K DVR would have multi-tuner UHD recording with Harddisk capacity more than > 1TB.
Also waiting to hear on 4K Antenna size..As my multiconnectin HD DVR+HD STB has a bit bigger d2h HD(90cm i guess) antenna which giving me better Picture and signal strength quality till now..!!!
