i just triedthis amazing software called DVD SHRINK it took about 30 minutes for encode a movie that took me about 8-10 hours to finish. the only problem that i had was that when i previewd the movie with POWERDVD I did't have audio. so all i did was to delete the ifo files and then created them using IFOEDIT and lo and behold it worked.....
just wanted to let you guys know in case somebody is having this problem...
