Hi David

thank you

I seems to me Tovid is only for disc authoring (disc readable by most 
DVD players). Not a general purpose transcoder.

== from Tovid wiki ==
Tovid is a collection of GPL video disc authoring tools; it can help you 
create your own DVDs, VCDs, and SVCDs for playback on your home DVD player.

How are the options with transcode?

How to do it with ffmpeg?

$ tovid -in otto_walkes_apple_vs_pc-Muqu85jzsSU.flv -out 
otto_walkes_apple_vs_pc-Muqu85jzsSU.mpeg4

gives me:

$ file otto_walkes_apple_vs_pc-Muqu85jzsSU.mpeg4.mpg
otto_walkes_apple_vs_pc-Muqu85jzsSU.mpeg4.mpg: MPEG sequence, v2, 
program multiplex
