A simple question really.

I have the following wall plate:
WP-10P1D-WH from http://www.infinitecables.com/pr_wall.html

A vga insert goes in the double slot obviously. The rest of the inserts will contain the following:

5 RCA type jacks
1 Ethernet jack
1 F-Type connector
1 Toslink connector
2 HDMI connectors

My question is this. Is there anyway I should or should not place these inserts so as to minimize interference between lines or so forth?

Nope. They are all low voltage so they should be fine placed however they fit best.

I figured as much.

Cheers!
