Okay, you don't know shit about what HD is right ?
In HD RAWs the number of lines (or vertical pixels for you since you seems to be lost once we talk about something out of your PC field) being displayed is either 720 or 1080.
the number of lines in SD RAWS (or standard TV for you) is more like 400 or 576 depending on the source.
So, does numbers speak for you now ?>>How do you make drawings more "HD"?
Sorry to say it, but this is a really stupid statement... since the shows are made to be displayed on the HD broadcasts they are draw so that they use the HD aspect.
Still not convinced ? dl a HD raw then compare with your standard SD subs, of you got eyes without the need of binoculars to see shit you'll get it immediately... "Ooooh, shinny crispy colors and sharp details"
