I have my Roku player hooked up to my main TV via HDMI. The composite video & LR audio outputs are also hooked into a digital modulator which combines into my cable system and feeds all other TV's in my house on channel 120. I control the Player with the universal RF remote from my main system. Of course, I don't get HD on the modulated TV's but the picture is still pretty good and I don't need to change inputs on the TV. Modulators can be had pretty cheap and 1 modulator will put the Player on ALL TV's in your house. Good luck.
If the player cost 1000 dollars I might go through all that to set it up for more then 1 TV, but since it only costs 100 bucks, I would still just buy two of them. I would rather have the option of watching two different things at once than just having the same program display on multiple TVs.
Absolutely. People need to keep some perspective here. To buy and run that much cabling or use some other doohickey to transcode the signal or to use voodoo to turn someone into a zombie it really doesn't make much financial sense when another Roku is only $100.
In my case, it works well. I have a small house with 3 TV's and only watch one at a time. As for cabling, it's only one piece of RG6 from the modulator to the cable head-end. Also, it's really a 3-channel modulator so besides the NP I've got a Tivo on it as well that I can watch & control in any room.
Opinions are like a**holes. Everybody's got one.
