| 837506 | 2009-12-07 22:18:00 | Purchased a 10m S-Video cable which arrived today however the video on the computer has some interference (I think it's termed as interference). The interference doesn't occur when I move the computer next door and use the 2m cable. Is there any way I can reduce this interference? |

In another building? Another room? Find whats causing it, try the 2m cable in the same room. Then see what else is in the room that could be causing a problem. |

| 837510 | 2009-12-08 04:08:00 | I think there might be something wrong with the 10m cable, the bars come up on the computer when I move it next door and when I plug the cable into the TV. | davidmmac (4619) | ||

| 837512 | 2009-12-08 07:16:00 | It could be that because the cable is so long, it's more inclined to pick up induced (acting like an aerial) stray signals from other cables and electronic devices (eg your TV and computer etc) and mess up the picture (you would not have this problem with a digital signal); computers especially can be quite bad for causing analogue signal interference, try moving it about or shielding it; check the long cable has continuity (a circuit) on the ground pins between one plug and the other. pinouts.ws Would there be any issues in running these from the Sky decoder to my computer for recording purposes (eg. are there any distance issues or would the quality degrade etc)? Looks like you are having said issues :crying. |

How would I go about "shielding" the cable? |

| 837514 | 2009-12-09 09:41:00 | The cable ground pins connect to the shielding in the cable (en.wikipedia.org) (or should do), that's why I suggested you check the ground pins make a circuit, otherwise there's not much you can do with the cable (perhaps run it through an aluminium pipe/conduit); what I actually meant for you to try extra shielding on was the computer (perhaps a Faraday cage (en.wikipedia.org) sort of idea, though this might be a bit extreme :waughh::)). Alternatively, there may be some way of transmitting the signal digitally (haven't looked into this, may be expensive/impossible). |

| 837515 | 2009-12-11 02:42:00 | Ok, thanks for the suggestions feersumendjinn, for some reason it seems to be Ok at the moment, but it's anyones guess as to whether it will be Ok in the near future :rolleyes:. Note to self: Next time I buy a cable, buy a digital one, don't fluff around with this analogue rubbish :rolleyes:. |
