What page are they on because your link directed me to page 107.
How in the world am I going to know what page they're on? I don't own a Vizio SV421XVT. You do! So... you're the one that's going to have to search. Or just post in that thread asking what some settings are and I'm sure one of the many owners there will oblige, but this thread is headed nowhere on its own because people are just going to tell you to use the search function or link you to other threads like I did.
