Satellite TV connection question
 

I have a Dish Network PVR that I use to signal (2) TV's. I currently go coax out of the sat box to a splitter that sends the same signal to (2) TV's. (1) TV is next to the box and the other is 70' of coax cable away at the other side of the house.

Could I use - both - the S video Out and the Coax Out at the same time to send video to both TV's, or would connecting the S Video cable negate the signal coming from the Coax?

I do not have a S Video cable to test this connection method.

I am trying to get the best picture to the TV close to the sat box and still slave off the signal to the other TV which is in a bedroom. I do not want to pay the fee for a second box. The UHF remote works perfectly through quite a few walls to reach the antenna on the sat box.

from my experience the coax will work with the composite (rca) and the s-video, it's when you plug in the s-video cable that it negates the composite (rca).
i don't have "dish" though so can't give you a definate answer.

I use both on my Dish receiver at the same time - RCA to my receiver and s-video to my DVD recorder.

Set it up this way so I could record a show to DVD while watching a DVD.

Now if I ran the s-video to my receiver and rca, the rca inputs would be disabled. I would prefer to run s-video as it is a better signal but I was having issues with movies that would have very dark scenes confusing the receiver (thought it had no signal) and getting a blue screen when using s-video.
