Released on laser and VHS only. Harmy has a 720p recreation, I think.
That is not true because they were also released on VCD.
VCD’s are SD only. As far as I know, G’kar and TB (and Revivax for ANH) are only in widescreen SD… 480p, and even then not full DVD quality. Upscaling them doesn’t do much. I’ve tried. You can coax a little more out of them, but not 720p (though presenting in at that resolution does produce the best results, it still isn’t DVD quality).
