How to calculate the size of mpeg2 file

[brainstorm]

I have about 2 hours of dv material and want to encode it with cce to mpeg2. But how to know how many minutes of variable bit rate around 8000 or 9000 kbps will go on one dvd. How to calculate the size of movie which will fill DVD to full.
How many space do I need to preserve for starting menues etc (authoring with ulead DVD Movie)?

Thanks!

From Doom9's miniDVD guide:...You can spare yourself the splitting trouble by do some quick calculations before en/transcoding: You'll be setting an average bitrate for the video and a bitrate for the audio - the latter is constant bitrate. ( video bitrate + audio bitrate ) * length in seconds = filesize....Remember to divide the results by 8 for number of bytes. I hope this helps a little bit.

There is a DVD-R bitrate calculator in Doom9's download page: "DVD-R Calculator". It might simplify things for you.

Good luck!
