control audio bitrates, resolution and video bitrates (150kbps-4000kbps <to go to 4000kbps, you have to click on the + sign in bitrate menu>)

best one, get the free XPRESS version (only converts videos, not DVD's) including all the formats that your computer is capable of (decode by codec installed on your computer)
