Well if you just want the credits you can rip the LAST vob file in the movie and then make a d2v file with that and then inside TMPGEnc double click on sourse range and get the parts you want. And if you just want the audio you could get that mpg file and open it with virtual dub and rip the wav. Or use the vfapi progam to frameserve and try to rip the wav directly.
