My grandson has 2 movies he always watches. I was bored so I thought I would put them on one disk so he could watch one after the other. Each movie was only about 85 minutes long. I reduced them both to 2GB size each. I then changed the VOB numbers so they would be continuous. I used ifoedit to create the new ifo bup files for the four vob files. The first movie plays and then it stops, I wanted it to go directly to the second movie. Is this because the bit rate may be slightly different on each movie?
