My objective is to take individual chapters off of different dvd's and compile them on to one. I used smart ripper to rip the individul chapters off of the original dvds ( by the way the individual chapters are music videos). I then imported the vob files into roxio 6 dvd builder, and created a new dvd. The problem is roxio encodes the individual chapters again and this makes the quality of the audio and video to go down noticeably. I then tried to use the vob's in nero 6. the problem there is that some of the vob's have the same name. So i tried renaming them with different numbers and now nero says some of the videos did not pass the dvd compliance. i tried to burn it anyway and it burned a data disc with vob files on it. need help. is there any way to burn with roxio without re encoding or do i use nero but how do i combat the problem with the vob's named the same. Please help.
