Aspect ratio for letterbox

[Dave Wood-4]

tcprobe gives on the original:

[tcprobe] MPEG program stream (PS)
[tcprobe] summary for video.mpg, (*) = not default, 0 = not detected
import frame size: -g 624x256 [720x576] (*)
     aspect ratio: 1:1
       frame rate: -f 25.000 [25.000] frc=3
                   PTS=0.2400, frame_time=40 ms, bitrate=9800 kbps
      audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x2000 [0x2000]
                   PTS=0.2400, bitrate=192 kbps
                   -D 0 --av_fine_ms 0 (frames & ms) [0] [0]

I've tried encoding with both ffmpeg and mencoder. In both cases mplayer will play
the file ok, but after dvdauthoring and mkisofs mplayer will not set the correct aspect
on the resulting dvd.

Any ideas?
TIA

Why are you bothering with letterbox? That's just wasting precious pixels.
Use anamorphic instead.

I'm not sure I understand you. The original file is already in letterbox.
Do you mean there is a setting to convert to anamorphic in dvdauthor, or
that I should convert before using dvdauthor?

Pity. Are you not able to get a higher-res version from the original source
material?

Not sure how to do that to be honest. Any tips?
