thanks - but i still got problems - which strings can i use for -vcodec and -acodec?

i'm trying to do simple conversion to work:

ffmpeg -i "test.mp4" -vcodec flv -acodec libfaad -s 176:144 -b 200000 -pass 1 outfile.avi

i am trying to convert it to maybe xvid/divx with aac/mp3 (something to play smooth)
