tovid doesn't recognise aspect ratio on mp4

[GoogleCodeExporter]

 have notices this before on several files that have mp4 extensions. tovid
will list correct dimensions of video then forget it when converting to dvd
- have a look at attached output and you will see what i am talking about.
You have to overwrite with -aspect option to ensure correct aspect ratio.

Just so there is no misunderstanding: the 'dimensions' (framesize) of the video 
is 
different than the aspect ratio.  All DVD videos have a framesize of 720x480 
(720x576 for pal) and it is stretched according to the aspect ratio when played.
The wording of your bug report makes me wonder if you know this.

Please provide the command you used with tovid - it appears that you used 
-aspect 
NNN:NNN to override the autodetected aspect ratio.

"All DVD videos have a framesize of 720x480 (720x576 for pal)"

Actually the DVD specifications allow a few other sizes, but the principle is 
the 
same: the result must be stretched by the DVD player to achieve the desired 
result.
