Don't think he is talking about a format problem. The channels he is talking about are broadcasting in something that looks like 15:9 instead of 16:9 and is leaving black bars on the right and the left when in normal mode. Not really sure if these are anything more than upconverted shows that are not being made full 16:9
It all depends on the show most of them take up the hole screen.
Some even take up the whole screen...
Yes I was in a hurry glad to know we have spelling and grammar police on the boards.
