PPV movies are normally in OAR (Original Aspect Ratio). Most of the time this is theatrical widescreen (2.39:1), which means it will be letterboxed even on a widescreen HDTV (theatrical widescreen is much wider than the 16:9 widescreen). On premium channels like HBO/Cinemax/etc, the movies are usually shown cropped to 16:9 so they fill the whole screen, however you lose some real estate off the sides. But you do still see theatrical widescreen occasionally there too, and there are some movies that were actually shot in 4:3, which will show up with black bars on the sides (pillarboxed).
