I'm trying to convert an avi to mpeg..except everytime i do i end up losing the sound of the avi and the video length is tripled ( the 33min avi is converted to a 1 hour 33 min movie) can anyone tell me what is going on? please help me. Thank you

The AVI specs are as follows:

Media Length: 33min. 35.932 sec.
Audio Format: MPEG Layer-3,135 kBit/s, 44,100 Hz, Stereo
Video Format: 640 x 480, 24 Bits, 48334 Frames,
23.976 Frames/Sec,184 KB/Sec, DIVXMPG4 V3

I used TMPGEnc(newest version) to Convert To MPG using the NTSCFilm VCD Template that came with it. If anyone can help please let me know.
