Hi Mokles
as you have the BUP IFO VOB files on your computer which are the files that are on a DVD
all you need to do is burn them to disc. download imgburn form here http://www.filehippo.com/download_imgburn/
then have a look at this page http://www.afterdawn.com/guides/archive/how_to_copy_dvd_with_dvd_shrink_page_5.cfm
you only need to do the first three steps then click burn
it will say you have not named the film but just close that if you do not need it and let it burn to disk
hope it helps
Paul
