This was the recipe I used to put a DVD extract onto the net, in case
it's of interest:
-------------
Use avidemux
Video: Mpeg4, single pass, quantize 5 (higher numbers less quality, 10
more or less unwatchable)
Filter: Mplayer resize (from 704x576 Pixel AR 16:9) to 296x136 (both
final dimensions must be multiples of 8, ratio to keep over-all aspect
ratio of movie with 1:1 pixel AR)
Audio: Lame, 80k CBR (lower numbers lower quality)
Format: AVI

This encodes about 20 minutes TV programme into about 50MB (2.5MB per minute).
--------------

By the way avi / flv is just another 'wrapper' so you still have to
chose a&v codecs.
