My TV is a Prima of America it's 2 yrs old and does 480, 720 up to 1080i
When i'm in the digital channels ( i live in Canada , and Cogeco cable is my provider ) i have the option via my TV - 4:3, 16:9, Panorama, Zoom
The Zoom button on the Motorola 6416 ( btw HDMI and component options ) is not enabled

..so any option to increase ratio is done through my TV.
My issue is when view HD channels ( and yes i am aware not all HD channels project HD 24/7 some HD station only do HD with certain TV shows )
Some HD shows are projected beautifully in HD quality but are in a 4:3 format with wide black bars on either side ! Some shos even show the H in the bottom right in the view in TV show ( meaning HD format ) and the D is actually in the black bar ) yet my TV when on the HD channels will only do either 4:3 or 16:9 it won't Zoom to get rid of the annoying Black bars !
Now i tried going in the ridiculous sub menu of these Motorola machine !
( absurd power off than hit setting button to adjust ratio etc ) and nothing helped if anything the picture could only go down in size a la 480 p got smaller option !
Sorry for the long explanation just very at my wits end. Now i had Bell Express Vu at one point and didn't have this issue ! As the Bell's reciever had a zoom option that worked on the remote it came with.
Now my guess is if Cogeco Cable or Motorola had bothered or had a way to be able to activate the zoom option on the receivers remote i'm guessing i wouldn't be having this issue !
enclosed as an example pis i made to show you what i mean about the quality and H in the picture and D in the black bar
