Nice table!
There is however one point where I disagree with what the table states and that is the SVCD PAR.
The table assumes the 480x576/480 pixels used in SVCD make up a 4:3 frame. I'm pretty sure though, and that's also what I have observed capturing the output of DVD-Players playing a 480x576 test video, that these 480 pixels are simply a downsized version of 720 which means it has the same characteristics as 720 (wider than 4:3, scanline length is 53.333µs).
Therefore the PAR of PAL SVCD is 177/108 and the PAR of NTSC SVCD is 15/11.

Edit: Those are for 4:3 video, 16:9 is as follows: PAL 177/81 NTSC 60/33
It's actually just the PAR for 720,704 multiplied by 1.5.
