In DVD2DVD mode I try to set DVD size to 2100 in order to fit 2
movie in 1 DVD.

In bitrate I set CD size to 2100, but the program calculate for
4480. Lookin in .d2s file I see average and cut size calculated as
4480.

I think this is a bug. Here it is the log:

If your DVD sources are similar - ie same format (PAL/NTSC), same aspect ratio and so on, you may find this thread useful
