I have my home theater in the basement and my wife and I watched everything down there including regular TV. We finally decided we didn't like sitting in the dark every night so I got a 50" flatscreen for the living room.
Instead of getting another DVR for the living room I wanted to run the signal from the existing DVR from downstairs to upstairs.
I found a device on Amazon (Tripplite B136-100) that used a single CAT-5 cable to extend component video and audio. It did work but the picture was less than ideal and had interference bands throughout the picture. Most of the time I couldn't see them but the times I could see them were annoying. For some reason CBS programming was especially bad. I think part of the problem was there was no amplification of the signal.
I did some research and found some options that used two Cat-5 cables to transmit the signal and had amplification but they were in the $300 (and up) price range.
As a result I ended up doing some research and found that I should be able to get away with 75ft cables for component video and stereo audio.
So I decided to try these cables. They arrived yesterday while we were watching TV. I took a few minutes to swap out the Tripplite adapter for this cable and the difference was astounding. The colors are more vivid and the interference bands are gone.
I wish I had tried this option first as the Tripplite adapter was $55 and the 100ft CAT5 cable was another $30. I will be buying another one of these to connect the DVD changer. Then everything we can watch downstairs will be watchable upstairs.
Now I have to do is "bury" the cable which just means getting it down the wall to the basement and over to the home theater area but that should only take about an hour.
If you are able to run these cables it definitely seems like the way to go.
We have a DVR HD receiver in our living room and we wanted to get HD on our kitchen TV without hooking up another receiver. I contacted them and they recommended these cables and we ran them down in the basement across and up to kitchen and now we have an HD picture in our kitchen. Great service and product and price!
Works perfectly for what I need. Used to run satellite signal to the bedroom so I can watch dvr recordings (before they came out with the new thing they got). Used one of the audio cables as a digital coax audio line. No visible/audible loss.
Cables a little rough to run since it's very large but managed. A+
Had to replace an in-wall el-cheapo 75' component video / audio cable. With the former cable, I was getting interference at 480p (looked like reflections in the cable).
With this cable, the signal is clear and strong with no signs of any interference. I will use these cables for in wall aps from now on.
Took one star off because the connectors' soldering is fragile and on two of this type of cable purchased previously, a lead has come off one of the audio jacks. No problems with the recently installed cable, however.
These cables are noise free, which is the main thing when running 75-foot of component video cabling.
For those running in walls, these cables are thick but managed to get the five RCA plugs through a 1" conduit. Had to separate the cables and run them one at a time (so the plugs would fit).
Only down side is that the white audio plug on two out of the three cables I have has had a loose connection. I suspect this happened while I was pulling down the cable through the wall, but it is strange that it is always the white audio plug. A soldering gun and a new connector solved the problem in both cases (don't try to solder the old plug unless you are really steady at soldering).
It was only for the broken plugs that the rating dropped to an 8. Otherwise this would be a solid 10 for how clean of a signal I'm getting.
