    I will be having a component cable and power cord running for about 25' feet across the ceiling. How far apart should I keep them so that the power cord doesn't affect the picture quality?

    I will probably get the Blue Jeans 1694A cable: http://www.bluejeanscable.com/store/component/index.htm

    Thanks.

    Also, is it fine if they run parallel within an inch of each other for a distance of a feet or two and then spread apart?

    The 1" parallel run MIGHT be a problem. Generally, you want to make sure that power cords cross a/v cables at a perpendicular angle. But this is usually more of a problem with speaker wire that isn't insulated as well.

    But another issue that is more easily resolved is your cable choice. Since you'll be running the cable in the ceiling, you probably want to use Belden 1695A (also available from Blue Jeans Cables) that is fire-rated for use in plenums. This keeps you up to building code - if you were to have a fire and your insurance company found non-fire-rated cable in the walls you might not get your money.

    Here's an article that might help you out: http://www.bluejeanscable.com/articles/humrejection.htm

    Pay particluar attention to the section where they induce a low-frequency, high energy EMI to various cables. They used an extenstion cord strapped to the cable, which is essentially what you'll be doing. They seem to conclude that Belden 1694 (or similarly 1695) strikes a good balance between RFI and EMI protection.

    You might want to drop the guys at Blue Jeans an email before you order. They can probably tell you exactly how far to space your cables.
