If I use TMPGEnc ti split my *.avi so I get i.e. 2 *.mpeg2 files. How I will know what size those files will be? => How many minutes *.avi can fit in 1 cd after it has been converted to *.mpeg2? (need to know the minutes because prog only shows time line where to split...).

Avi quality is very good and if it will goes in 2cd - like to get best quality as possible.
