I'm not gonna start a new topic

This is a newbie question, is mod16 compulsory for x264 like it is for XViD (for best compability)?

and another question, are these values correct for SAR
I learnt it from YAMB "View and edit Command Line"

16:9 NTSC = 40:33
16:9 PAL = 16:11

Picture aspect ratio is really very confusing!!!
how come 16:9 for DVD is 40:33 for MP4?
Are there any good guides for this, I tried to do google search and found a few websites, still don't really understand....I can find no website mentioning 40:33 or 16:11!
