[MPlayer-users] problem encoding a compliant DVD from an XviD source movie

[Prabu(A.G.Oliveira)]

Hi friends from Mplayer&Mencoder list!!!

I'm a beginner and I've been trying hard (without sucess) to encode some 
movies to see on TV.

for example, one of my source movie is:
 
Lost_S03_E01.avi - VIDEO:  [XVID]  608x336  24bpp  23.976 fps  1019.6 
kbps (124.5 kbyte/s

And I would like to put it on a dvd (with subtitles) to watch on tv.


After having gone several times through the man pages an some others
docs on the net, I was confident thinking having understood:

      - About pixel/display aspec ratio matters.
      - About the meaning of  720x480 NTSC DVD requirements and why a
        640x480 square pixel should be streched (scaled) to
        720x480 in order to make a compliant DVD frame....
 
 but sadly, my tests are telling me that I didnt!


The best result I could manage to have, I got with the following script:

( Plays beatifully on the computer but on tv I get a expanded screen my 
subtitles go down out of view
  and I loose image on top, bottom, left, and right, because the image 
is displayed bigger than what it should be)

also I have tryed many, many others -vf combinations like...
#  -vf crop=608:336,scale=720:417,expand=720:480:0:5:1,harddup \
# -vf crop=608:336,scale=640:-10
# -vf crop=608:336,scale=720:-10

also I tryed several (3/4, 3:4 ..) aspect ratio arguments, with and 
without telecine.. etc, etc....

and as I told above the best result gave me a too big image on TV.   :-(

oh yes I must also say that Im using dvdauthor and k3b to write the 
media on my debian sarge box.

$   dvdauthor -o /tesdir mymovie.mpg       # I think this should be 
enough,  shouldn't it??


So please, would some one give a hand ?!
