Component video requires 3 cables (blue, green, and red). You can substitute any old RCA cable set for them (red, yellow, white). But, you will get better quality video if you use better quality cables meant for component video transfer.
And if you want stereo or Dolby Surround Sound coming out of your DVD player, you can use 2 RCA cables. You need Optical or Digital Coax for Dolby Digital and/or DTS.
