Hi m4tt and welcome to CD Freaks and the DVDFab forum! The options to do what you request (except for the .MPG file outputs) are already available on the Configure screen using the Generic profile. You can select fixed bitrate and just type in the value you want into the video bitrate box or use the slider. The audio bitrate can only be changed if you use the Xvid+MP3 profile, which you select with the drop down box near the top of the Configure screen. Hope this helps. Post again if not.
