Ok, I've done this before but being a moron, I forgot how I did it. I'm converting a PAL to NTSC dvd. When I rip with either Smart Ripper or DVD Decrypter, I end up with an AC3 file. I've converted one movie before and somehow I ended up with a wav file. Then I just loaded it into tempengc along with the video file and reauthored it. But now, I always end up with an ac3. Is there any way to do this again? What am I doing wrong?
