Really?
Reading your op:
(1) Split the component cables from back of cbl box with monster splitter
(1a) send one side to rec w/ coaxial sound, then vid to tv w/ (all component cbls)
(1b) send one side to tv (vid 1) using rca sound outputs for the audio
Reading your post one discerns the following:
You split 1 into 1a and 1b. How do you not understand the confusion? I think I now understand what you were attempting to write...you did not mean to meld 1 with 1a and 1b. I'm not trying to be trite or the grammar/composition police, but...
Anyhow, I think I now understand your question, and I have given my resposnse. Cheers.
