DVD Audio Ripper 5 - Chapters?



Hi Guys, 1st time on the Forum and looking for some help. I have a few live concerts that I have recorded to DVD with my Tivo and I would like to burn them into a audio CD. ImTOO DVD Audio Ripper 5 works great to make them into MP3 files, only problem is because it’s not a factory DVD and does not have any set chapters, it automatically sets a chapter every 5 minutes for the enitre hour long DVD. On a live concert this splits various songs onto different chapters. My question is, any way to alter the chapter length before or after ripping?
Thanks for any help, this is the first time I’ve tried this so I don’t know much about it.
