I believe those are all. I don't know what resolution those are supposed to represent. Can anyone help me?
I'm pretty sure these are all SDTV-era resolutions, so 480p and less (technically NTSC is 720 x 486, and then skewed either to 4:3 or 16:9 by stretching the pixels). 4:3 refers to the aspect ratio, meaning it was designed to fit older TVs (before widescreen). LB refers to Letterbox, meaning it has black bars on the bottom to fit 16:9 content in a 4:3 image. SD is also alluding to the fact that it's SD-resolution, perhaps still being broadcast (upscaled) to HD. All of the i, ip, p, and so on refer to the sorts of frames in the broadcast.

Anyway, bottom line is, for all of these resolutions, "HD" broadcasts were upscales, and any Blu-Rays may have been upscales as well. You could probably stick with DVD-level encodes for this content; 480p or less.
