Heeelp!! Mpeg2->DivX4.12 audio problem

[maz2002]

I have an mpeg-2 file (video+audio) and I am using Xmpeg 4.5 to convert it to DivX. I have already installed DivX 4.12 and Radium audio codec (mp3). I am using the 2-pass process. I select audio compression, Fraunhoffer and 224 kbits/s since that is the rate used to create the mpeg-2 file. After conversion, the video comes out ok but the audio is choppy; the sound comes and goes at a rapid rate; it isn't smooth and it causes the video to get a little jerky too. What am I doing wrong??? Any help is greatly appreciated.

thats xmpeg for you

u need to extract the audio from the vob/mpeg2 file

then open the video in vdub. select direct stream copy for the video. now dont choose 'avi audio' thats the choppy one. instead choose wav/ac3 (in using nandub). then choose 'full processing mode' for audio and choose the prefered compression

finally save the avi

thats a full proof plan

grrrrrrrRRRRRRRRRRRRRRRRRRRRRRR................DIV X v4.12


do u want better quality and LOWER file size?

use DIVX 3.11alpha!!!

To keep the file size to a DESIRED file size, and EVEN BETTER quality, DVD or better....use nandub 2 passes.

So how do I extract the audio only? (or separately) ?

Soz if this is a daft question.

Thanks to UncasMS - just found the answer to my own question.

Downloaded Vob2audio at http://www.monfree.com/appl/default.asp

Oh but you did!!!!

i prefer extracting sound from vobs via vob2audio to wav and then i use wavelab for further 'enhancement'.

You said it in thread below. Thx again m8.

I'm still having no luck with this. (BTW, changed my username).
Let me re-explain the problem. I have an mpeg-2 file (video+audio) created by a TV-tuner/capture board. The file plays fine in MS MediaPlayer6.4 . But VirtualDub cannot open the file!? I don't know why!? So I tried Xmpeg4.5. I can open the file, but when I right-click->Run->audio player to check the audio, the audio is choppy. When I continue with the conversion(DivX4.12), the resulting avi file has choppy video and audio. So I tried it again by sending the video and audio in separate streams to the hard disk. This way, the video is choppy but the audio is fine. Why? I've tried different iDCT (opt.MMX, miha ref.), key frame rate,but no luck. Is there anything special I have to know about the mpeg-2 file?
The reason I chose Xmpeg4.5 is because it's an all-in-one application. Is NanDub the same? Will it also take care of the audio?
Thanks for any help.

all in one appz are never the best

to open it in vdub u could frameserve the mpeg2 through dvd2avi (i think)

try it and it should work

SUCCESS!!!
I finally got it! But I had to use Gordian Knot, which uses VirtualDub and NanDub. And Doom9's guides.
Thanks very much for the help.
