Can you use coax for video with s-video adaptors and will it improve the picture?

[Diamond Dog]

I just got one of those new Dishnetwork boxes that control 2 TV's with one unit and have 2 seperate DVR's built in that run independently. Its pretty slick.

For the 2nd TV there is a coax out and it runs from my master bedroom to my kitchen through a coax cable. I had a crummy TV at first, so the picture and sound looked ok. I just put up a stereo lcd tv and now the picture doesnt look so hot and the audio is in mono.

The cables are already run through my house and through walls, so running more cables from my bedroom to my kitchen are not an option. Everything is running off this one coax cable to my kitchen.

The back of the Dishnetwork receiver has both RCA and s-video outputs. Is there an adaptor for s-video to F (coax) that I could put at both ends of the coax and use the s-video out on the receiver and s video in on the TV? Would this improve the picture quality?

For the audio, I was thinking of using a wireless transmitter that would plug into the rca outs in the receiver and the RCA ins on the TV. Hopefully someone makes speakers that could accomadate this setup that would clip onto my TV? Anyone make a good stereo wireless transmitter that would fit the bill?

My LCD is hanging on the wall with nothing around it. It looks so clean as there is only a coax cable and a plug that are behind the receiver so you see nothing but the LCD. I want to keep this look.

The distance from my receiver to the kitchen LCD is about 100 feet and it would be next to impossible to route more cables as it has to go through multiple walls with no crawlspace or attic access.

Anyone have other suggestions?

Thanks in advance

S video has 5 concuctors. 75 ohm coax has two, including the ground. I cannot fathon an adaptor to convert one to the other. If you are intent on using that single in wall connector for a video signal. your onluy options are either RF (which will work but will probably suck) or yhe yellow RCA composite video jack. The length of the cable may or may not impede tghe signal but you might be able to score some kinda video amp.

I don't suppose another sattelite box entered your mind, did it?

The reason I dont want another receiver is because right now there is just my LCD on the wall with nothing around it and I want to keep that look. You cant even see cables as the plug and coax are behind it.

Also there is a $6 dollar extra fee for another receiver I would like to avoid

radio shack has an adapter that goes from a female RCA to a female S-video if i remember right it was expensive. i don't know about the picture quality.

Adapting from s-video to coax and back to s-video would completely negate any and all benefits of using s-video in the first place. The whole point of having multiple wires in s-video cable is to separate the different components of the video signal. No sense in separating, combining, and reseparating. A good rule of thumb for video as well as audio is to avoid using adapters whenever possible.
