79. Both vertical and horizontal resolution is tossed.
If you're throwing away every fifth line, then you're also losing 20% of the horizontal resolution as well, which leaves the aspect ratio intact. You're forgetting that in each case, you're dealing with square pixels. If you're displaying a 720p image on a display only capable of 480p, you need to throw away 1/3 of the vertical lines of resolution. However, because you're only capable of displaying 854 pixels instead of 1280, you need to toss 1/3 of the horizontal resolution as well. You obviously no as little about video conversion as you do about the events on 9/11. Please, use YOUR brain.
