The only thing that those programs do,is re-encoding the film as vcd,svcd or divx,so the amount of data is much smaller.....that way,it fits on 1 or 2 cd's,however,most of the times,the quality is poor and those programs are rather expensive.
here you find all the info to do it yourself,and to get much better quality....
But burning a dvd on a cdburner is impossible....
