What we're watching: What a country! You can go from being the President of the United States to an Allstate front man to a U.S. Special Forces commander all in a single acting career. We're talking about Dennis Haysbert, who would actually get our vote if he really did run for President; what a decision-maker! Haysbert kicks off the premiere of "The Unit" tonight on CBS in 1080i at 9 p.m. This looks like another high-action thriller series but has the twist of also encompassing the wives of the Special Forces personnel. We'll call it "24 Desperate Housewives" for now.

We're also intrigued by tonight's ep of "House" airing in 720p on Fox at the same time. If we interpreted the previews right, a dead woman must be cured of something so that her organs can be used to save someone needing an immediate transplant. Looks like we'll have to record one of the two shows, but which will it be?

Our traditional high-def listings continue below.
