Hi!

My system is FreeBSD and I have problem to plays converted web to dvd format 
on standalone video player. It is "chocking". How I did conversion:



ffmpeg -i xy.webm -aspect 16:9 -target ntsc-dvd dvd.mpg

Sometimes I have muc more "WARN"

and
dvdauthor -o dvd/ -T

and final burn iso with:

growisofs -Z /dev/cd0 -dvd-video dvd/

And as I wrote above when I play DVD on the standalone player it is chocking 
and some are not usable to watch but if I play on computer it works without 
problems.

Thanks in advance.
