While I do theorize that that objects can float in orbit to an extent, the space station I would suggest is too large to be suspended in a circular orbit around the cylindrical earth. I believe all footage of the interior of the ISS is simply taken from a falling airplane, similar to how they simulate anti-"gravity" in movies. They piece it together and make it similar to how they make these films. For the live feed, it is either a low-faring aircraft or a possible smaller satellite in circular orbit, but if you are to look at it, you can see it is obviously filtered. Take a basketball and rotate it steadily while recording. Do you see any "fuzzy" edges or a pitch black blotting out the surroundings? Now look at NASA's live feed. You can tell it is stretched, fuzzy around the edges and anything beyond the earth is pure black. It is evident, the ISS is a fake.
