I've been trying to fit a movie on one CD-R by changing the bitrate to a lower rate. I've had success in the past with other movies, but this time, after hours of converting, the output file results in the same file size as the input file. I am using TMPGEnc's bitrate calculator and it reports that the resulting file should fit easily on an 80 minute CD-R. Original bitrate is 1150. I am converting to CBR 550. Any help would be appreciated...
