This patch will fix/change:

1. avctx->sample_aspect_ratio.num == 1 and 
avctx->sample_aspect_ratio.den != 1:
There is bug in old comparison, so with this aspect ratio for example 
1/2 old alghoritm will produce aspect ratio 1/1

2. Old algorithm also does compute with negative numbers, which should 
not be used

3. Always reducing DAR width and height is very useful for future use 
when we will be monitoring aspect ratio change for reseting encoder...
