well im just going to assume you mean converting a standard dvd movie into XviD (.avi) format.
i use Gordian Knot myself but it’s not super easy to use but will give you good quality results.
but basically if you make a 2 CD (i.e. 1400MB file) you will have to use VirtualDub to split the file so that it fits onto 2 CD’s which takes some trail and error.
but if your trying to make that 1.08GB file (im assuming it’s a XviD .avi file) fit onto a CD… i would just split it with VirtualDub (MP3 Freeze version) … not super easy to use but once you know what to do it’s actually pretty easy… but splitting it so that you take up pretty much the full disc can be a little bit of trial and error finding the exact point to where the 699MB range is at… i usually start roughly around the half way point of the film and start guessing… and once it outputs the file based on the file size you can usually get a rough estimate as to how much one way or the other you have to go.
p.s. but if what i was saying (DVD to XviD) is what your trying to do… your better off getting a DVD burner since you can fit like 3-6movies per DVD disc that way and it’s MUCH cheaper than burning to CD’s… cause those same movies would take anywhere from 3-6CD’s to backup that data and most CD’s are roughly 20cents a shot (i.e. cost you anywhere from $0.60 to $1.20 vs a DVD which is around $0.30 for same DATA)… do the math and it’s much cheaper to just burn .avi files to DVD+R discs vs CD-R’s.
