I don't think your process is wrong. Maybe your burning speed is too
high. Some DVD players are very picky.
BTW, I use the following command to make dvds and it works reliably.
Saves a step in the process, since it makes the ISO and burns it.
directory=<directory holding VIDEO_TS>
growisofs -speed=8 -dvd-compat -Z /dev/dvd1 -V DVD -dvd-video $directory
Good luck
