One thing to remember here is that you have to start thinking in 16:9 terms and not 4:3. I think I heard you say that you don't have any way to monitor the signal and I also take that to mean you have no 16:9 monitor nor way to letterbox 16:9 on a 4:3. If not, and you haven't really seen what happens when these different modes are engaged, then I can fully understand your confusion here. Been there. Done that! You are NOT alone.
Let me see if we can get on the same page of terminology. If I am understanding correctly:
"Full Width" is standard 4:3 in 4:3
"Full Height" is a true 16:9 frame with a 4:3 picture with sidebars
"Anamorphic" is where a 16:9 picture is sent in a 4:3 frame.
OK. If this is all correct, here is what you should see in each mode on a 16:9 or 4:3 letterboxed | normal 4:3 monitor
Full Height - Stretched - a circle that is fatter than taller | normal 4:3 on 4:3 - a round circle in 4:3
Full Height - normal 16:9 - circle that is round | Circle that is tall and skinny on a 4:3
Anamorphic - normal 16:9 - round circle | circle that is tall and skinny
Now, what we did here to keep people from manually switching 4:3 and 16:9 was to tally off the master switcher (we have a GV Master 21 analog switcher) to a Evertz 4 source SDI router and to the Teranex GPI for 4:3 16:9 port since FOX duplicates the programming on both analog and digital receivers. When master hits net on the Master 21, it also triggers the network input on the SDI router and triggers the 16:9/4:3 GPI on the Teranex. When we switch off net, it triggers the Evertz back to the upconvert input and triggers the Teranex back to the 4:3 mode. This way we never have to worry about aspect ratio on net verses everything else. Our tentative plan for when FOX goes 720p next year is to run the Teranex in 4:3 with side bars all the time and just switch the output of the upconverted 480i to 720p with the network 720p signal dropping the aspect switch on the Teranex since the HD encoder stays in 720p 16:9 mode 24/7.
If any of that helps, feel free to use it, Billy. If you would like to talk to me directly then feel free to PM me and I will give you my phone number and if I can help, I will be happy to.
