DVD to PPC was one of my first purchases when I bought my PPC in October 2004.
I was pleased with the product and the output until I learned more, and tried other methods.
Granted, DVD to PPC version 2 is out now, which may make a difference. Eventually, I wasn't pleased with the quality of the end product (even when selecting "high quality"), the "out of sync" problems I experienced, and the time it took to encode a movie. I had legitimately bought this software.
I tried a few other methods, including the DVDShrink->PocketDivXEncoder route. Much faster, better quality, still "audio sync" issues.
Then someone suggested FairUse. I tried several levels of recording, and as I've said over and over...80kps audio and 250MB movies set on "auto" does the trick...and has only not worked perfectly in three occasions:
1) The "Great Outdoors" wouldn't work. I have no idea.
2) For some reason, MIB II didn't copy right. I'm going to try again today.
3) The LOTR extended versions all show "subscripts" with writer/producer information on the resulting files (they flash on and off from time to time). When I wrote on the afonic forums asking about this, the webmaster himself locked me out of the forum and told me I shouldn't rip illegally downloaded copies of movies (which I had not done).
So, all I can say is that the webmaster at Afonic leaves something to be desired and that I don't suggest going there for any kind of support...but I do support the program FairUse as the best option at the moment...for free (although I paid the donation for that, too)...although it can be very slow on older PC's.
Give it a try.
