My solution is not likely to be of much use to you, I'm afraid. For a long time, I had pieces of blue painter's masking tape around some of my cables (including PCA's) just behind the connectors with notes identifying the associated gear written on the tape with a black Sharpie. It helped to remind me which cables were coming from or going to the VCR and which were from the cable box. Slightly tacky and sometimes a bit cluttered looking, but the tape doesn't leave any adhesive goop on the cables and sticks to itself very well. There are much cleaner looking methods of cable identification, many of which may be available from computer supply sites (I found some stuff at CDW.com from Panduit and Leviton that might have potential), but I've never seriously pursued them. If you find something, I'd be curious to hear about it.
