What is the maximum length of an RCA cable before signal degradation?

I want to know how long the RCA cables (video and audio) can be, before signal starts to degrade. I have a DVD player in one room, and I want to connect it to a TV from another room. Distance is considerable so I want to know limitations

Signal attenuation will depend on quality of cable for that distance. I would recommend RCA cable constructed with RG-59 coax cable (Radioshack). They are small diameter cable, yet very good for longer runs.

In theory, it probably degrades with each additional millimeter of length.

In practice, it would have to be a hell of a long cable before the man in the street heard any difference.

I run 20' cables from my preamp to my electronic crossover. I've never noticed any degradation in the sound. Of course, I don't use bargain basement cables. I use a mix of DH Labs Silver Sonic BL-1 and Air Matrix.

My preamp is positioned directly to my right. The electronic crossover and digital parametric equalizer are on a small stand between my speakers (~10' away from my chair). My subwoofer amps are on separate stands next to each subwoofer and the amps for my main speakers are directly behind them on stands.

I prefer long IC's and short speaker cables.

Video won't be a problem. Audio really depends on the output impedance of your DVD player. The higher the output impedance, the sooner you would see degradation. If you are under 100 feet, I don't think I would worry.
