<font color='#000000'>I have tried audio/video cables for both applications and saw no difference whatsoever. That is, I have tried audio cables as component cables and vice versa with results being virtually the same. One cable is supposed to be 50 ohms and the other 75 ohms. Apparently in my system it makes no discernable difference.
I used 3 audio cables as component video cables just as a test (curiosity). The HDTV I connected them to was a Hitachi 65S700. The results were excellent.</font>
