It sometimes has heavy blocks on fast moving scenes since the encoder spends 
most bits on interlacing-lines ...

+ It will feature a config option to let the user decide which encoder to use 
(lavc / divx / xvid) and use the appropriate syntax for mencoder.
+ Correct Aspect Ratio sacling in case of 16:9 material (current is not 
exactly :-()
+ Some bigger internal changes not to be noticed by user (hope so)

So, cropping is heard to do automatically, since i have no way to analyze 
pictures :-( Rescaling could be added depending on wanted_size and length of 
the movie ... But that's future todo :-)
At the moment i'm focussing on encoding interlaced xvid which gives BEST 
results for series (like Star Trek)
