Yeah but what about the info above the table?
"Note that sources differ on PARs for common formats – for example, 576 lines (PAL) displayed at 4:3 (DAR) corresponds to either PAR of 12:11 (if 704×576, SAR = 11:9), or a PAR of 16:15 (if 720×576, SAR = 5:4)."
That's what I'm still vague on, because both of those examples give you a PAR of exactly 4:3.
It seems to me most (PAL 4:3) DVDs use a PAR of 16:15 regardless of whether the extra 8 pixels each side contain image or not, but I'm still trying to understand this properly.
As a side note, a bit more browsing through the same wiki page led me to the sight below where they say the HDMI spec specifies an exact 4:3 or 16:9 aspect ratio and refers to the way anamorphic SD video is upscaled.
If it's true maybe it's another indication that exactly 16:9 and 4:3 are more standard than the official standards these days.
