Chuck, the success or lack thereof, with the Key Digital device is largely dependent upon your TV. I did use it for awhile on my Panasonic Tau, and it was the only one that worked UP TO A POINT. The reason I say that is that the hi def picture was fine but the non HD material displayed sidebars that were too wide on the Tau. There was no fix for that short of getting a STB with component outputs (which I did). All is fine now. It's hard to predict what your result will be with a different set.
