Bad frames + vbr audio = problems

[aram12]

After I use vdub-mp3 to delete the bad frames and then save out the new avi with both audio and video direct stream, I get an avi that no longer has vbr audio (for one thing, the error message doesn't pop up on virtualdub), and thus has awful sync problems...how do I successfully remove bad frames from a an avi that has vbr audio?

EDIT
I know that sounds like a silly question, because vdub-mp3 is designed to work specifically with VBR, but there you go.

Save audio using direct stream copy.
Set Audio-> No Audio
Set Video->Scan for errors,
Save avi file with no audio.

Load new Avi, set Audio_.wav audio, select previously save file,
Select File->save avi.

Just an idea, might work.

I did as you suggested and its still out of sync. So just let me get this straight...what SHOULD work is...open up avi in vdub-mp3...direct stream video...check for errors...create offsets on keyframes...hit delete...direct stream audio and video...save avi...load avi into regular virtual dub...continue as normal...problem is that "saved avi" is completely out of sync...in windows media player and in virtual dub...its like vdub-mp3 just wiped out all the vbr and rencoded it...which makes no sense because vdub-mp3 was designed specifically to deal with bad frames with VBR audio...it doesn't make any sense that it couldn't effectively save out the avi...

And I've just realized that in all the encoding I've done since vdub-mp3 came out...I've NEVER successfully encoded an avi that had bad frames...I've used vdub-mp3 to find that there are NO bad frames...but I've never actually gotten the whole delete bad frames process to work...I've read practically every post and guide on the subject and good lord it seems more straight forward than most things...please help...

Is it DIVX or XVID ?

Not quite what I meant.

Save the VBR audio out on its own using Audio->Direct stream copy, File->Save as wav. (I Know this file will have a .wav extension, but it will still really be the VBR mp3 audio as in the original avi)

Then set Audio to None. Fix the Video and save out using file-> Save AVI. This file will be silent.

Now open the new Avi (the silent one with the fixed video), Under audio select wav audio and select your previously saved VBR audio file, now do file->save avi.

It's divx.


Bug-

Sorry I confused you...I followed your steps exactly as you specified and it didn't help...I then proceeded to list (in my post) the steps as specified by the various guides throughout this site to make sure I understood the currently "easiest and simplest" way to take out bad frames.

I will try again, though, with your method and get back to you.

I did as you suggested again and the sync is way off...throughout the whole thing...not just after the frame drop, which is what I suspected would happen...any other suggestions? I can't believe this isn't working...I mean, that final avi that I get after completing your last step should play in wmp without sync issues right? why would deleting a few frames cause the WHOLE audio to go out of sync?

open file in vdub. do direct stream copy of audi and video.save as new.avi. take the new avi and open in vdub. go to audio check full processing mode. go to audio again and check conversion. check 44100, hi quality, 16 bit stereo. save the entire file as new2. aviusing video direct stream copy and audio in the full processing mode
new 2 avi should now be in synch. check it before encoding.

So open in vdub-mp3, delete bad frames, save out avi...then do what you suggest with video direct and audio full process as per your instructions?

Thanks, secretagent...worked perfectly...that alternate method should go in a guide somewhere...
