Hi. I'm following the excellent guide provided to back up my XVid movie onto a DVD. I've followed every step on the guide but when I'm on TMPG Encoder's last step (Bitrate settings) I can't seem to fit 1 1/2 hours of movie onto an empty disk. I've selected Video resolution to 720*480, the audio bitrate is 384, but the % of disk capacity is always near 150% and there is no way to make it less than 100%! I've tried it but I cannot. The movie is on NTSC, audio is MP3, and although the movie is in 16:9 I've decided not to use that option on the wizard and selected plain DVD on the first step. Any idea what am I doing wrong?
