Forcing aspect ratio not working

[burcs]

I'm trying to force aspect ratio on some encodes but it's not taking. I know I can manually set it in mkvtoolnix but would rather skip that bit. I've set it to 4:3 but it ends up being 2.0. Using megui.

I also don't see an option for 16:9. Thanks.

Dar != sar

The correct SAR for a 4:3 DAR 720x480 video is 8:9. Note that 720x480 is often really 704x480 with 8 pixels of padding at the left and right. With that type of video the real SAR is 10:11. Keep in mind that not all players will respond to DAR/SAR flags.
