if i am only ever using one audio stream with a max bitrate of 224 are the following settings going to produce a file that plays, and splits properly:
max bitrate = 2480 min = 300 avg. max = 2400
???
thanx

From Q&A:

A: What dvd2svcd do to calculate the avg. bitrate:

1. DVD2SVCD starts CCE and load the avs file and save the project file (ecl) and closes CCE again.
2. DVD2SVCD opens the project file, and it finds the number of frames and the framerate in that project file.
3. Using the frames and the framerate dvd2svcd calculates the number of minutes the movie is.
4. Using the minutes, dvd2svcd goes through each line in the bitrate tab. When it finds the line where the minutes are between X and XX minutes dvd2svcd get's the number of cd's and the cd size it should use.
5. DVD2SVCD then uses minutes, number of cds and the cd size to calculate the highest bitrate to fill the number of cd's to the limit.
6. DVD2SVCD calculates the avg. bitrate, modifies the Project file, runs CCE loads the Project file into CCE and starts encoding.

Example PAL movie:

After loading the Project file dvd2svcd determines that the number of frames are 155547 and a framerate of 25 fps.

Minutes = 155547 / 25 = 6221,88 seconds = Rounded to 104 minutes

Line used in the DEFAULT bitrate tab will be line 4 since the number of minutes is between 100 and 120 minutes. So the number of cds to be used are 2 and the size of the cd's are 800 each.

As you can see from the above I now have all the figures needed to calculate the bitrate to be used to fill 2 cd's of 800 mb.
