Hi- I want to distribute HD from a central DirecTV DVR to multiple TVs via coax... I've been trying to find a hdmi modulator to QAM but nothing is jumping out at me... Brands I've never heard of, must request a quote to even get a price... Equipment I've seen seems geared to commercial applications & not home use
(1) is this an unusual setup? If so - what are more commonly-used alternatives?
(2) any recommendations for the modulator?
QAM modulators are not inexpensive -- $1100+ for up to 1080p (close to $900 for 720p), which makes it not that common. Many people use matrix switchers, which allows multiple sources to be selected for viewing on any of the TV sets.
Yep, unfortunately there's no cheap modulation solution... ZeeVee products would be the ones to look at, but for DirecTV specifically, you'll be better off with the Genie whole-house DVR and the small client boxes at each display, or just the (also small) HD receivers that can also pull content from a DVR.
The single-wire multiswitch setup with DirecTV now makes it easy to use the existing coax w/splitters setup in most homes. Yes, you'll have to pay the monthly box rental, but you'll get more functionality, and the $$ break-even is many years anyway.
