2. Anyone have any other ideas or recommendations? I need 4 video
inputs that are 75 ohms, I want to be able to choose which source is
displayed on the screen, and I want simple TTL control.

inputs with 75 Ohm terminations, a 74HC4051 1of8 switch,
and, if you need to drive 75 Ohm again, a 5 MHz wide 2x amp with
2 transistors.
.
