I just converted 9 mpg files in DiVXtoDVD for the first time. I somehow added the same file in twice so the file naming etc is all messed up. I was just wondering if i take the vob files i already have and put them in a program that will make a menu etc, does it matter what the file names are? can i rename the vob/ifo/bup files to whatever i want? will the menu creating program make me new video_ts.ifo/bup/vob files?
