JohnK,
Wow! The table you cited indeed looks very encouraging...
Of course, everybody knows that Cable TV companies send their 5MHz-bandwidth signal over many miles of coaxial cables. Although the bandwidth is up to 10 times higher in component video, a few hundred feet should be no problem at least in theory.
However, I hear and read so many horror stories about video cables picking up various forms of visible noise/artifacts, which has made me paranoidal...
At any rate, when it comes to cables, I am determined to spend absolutely no more than really needed! LOL
