Ok so i went through this sites little guide right but when i got to the Birate Settings, the file exceeds 8000 MBs wwhen its really only 750, i followed all the setting and everything. Maybe this will help.
If you are Trying to Fit this Movie on a DVD then you would have to set the Video bitrate to about 6500Kbs and then set the audio format to "Mpeg-1 layer-2" and set the bitrate to "192kbs" and then when you are authoring the Files to DVD it should Fit perfectly....
