encoding with TMPGEnc

[Dollarb29]

I'm kind of new to this and I would like to kknow how to use this encoder. I used smart ripper to rip the Dvd, and I was using TMPGEnc to encode but I didn't know where to find the audio for the clip I was using to test TMPGEnc. The mpeg came out fine but there was no Audio. What file do I plug into TMPGEnc from Smartripper to get the audio? Any help would be appreciated.
