If set to off, the 4 x 3 picture is shown as 4 x 3 (with side bars). But passed by the box as 1080i (adds nothing to picture quality -- in fact, may make it worse). You will likely not be able to use your TVs stretch modes.
If set to 480i: the picture is shown as 480i (via the set top box), and you can use your TVs stretch modes.
If set to 480p: the picture is shown as 480p (converted by the set top box), and you can use your TVs stretch modes.
If set to stretch: the cable box does the stretching (you probably won't be able to use your own TVs stretch modes).
Accordingly, I would use either 480i or 480p (depending on which gives you the best picture -- probably 480p). Either of these modes will allow you to use your TVs stretch settings (which are better than the set top boxes single stretch mode). And will allow you to view 4 x 3 material either as it was originally intended (or stretched to your preference via the TV's own stretch modes).
Thus, since 480i or 480p allow the user to maintain the most control (over both picture quality and stretch modes) -- they are the best settings.
Note that this has NOTHING to do with high definition channels. This setting only matters to non- High Definition channels.
