im trying to join 2 avi files but when i load the first file it says:-
vbr audio stream detected.
virtualdub has detected an improper vbr audio encoding in the source avi file and will rewrite the audio header with standed cbr values during processing for better compatibility this may introduce up to 14452ms of skew from the video stream if this is unacceptable decompress the *entire* audio stream to an uncompressed wav file compress with a constant bitrate encoder (bitrate:158.4 + 17.3kbps).then when i try to loa the second file it says:-the audio streams have different sampling rates(19801.00000 vs 19787.00000).ive used this software before and never had any problems.thanks andy

Search is your friend - VBR MP3 audio gets covered several times a week. Save the audio from both files as uncompressed wav files in full processing mode. Make sure they have the same sample rates when you save. You can now replace the mp3 audio with the uncompressed audio, and you should be able to join without sync problems.
Read my blog here.

it seems to me that a lot ov us dont realy know how to do this so if possible can 1 ov u clever peole show us step by step on how to change the sample rates and how to change the audio.screen shots would be great.thanks anyway for all your help but im no clearer on how to do this.

from the tool section find & download virtualdub-mp3, it is designed specificaly for vbr-mp3. open the 1st file then append the second, audio is by default to direct stream, set video stream to same. easier it can not get!

I have the same problem. (lots do). VDmp3 works fine, but when I convert the avi to mpg to put on a dvd, the audio is still out of sync. Any ideas?

BigBoogie, the AVI needs to be in sync in the first place. If you save the audio out as a WAV, it should still be in sync. Don't join the AVI files, that's where a lot of the sync problems begin. And as guns1inger said, make sure the sample rates of the two files match.
If your final destination is DVD, then encode each part separately, selecting the WAV files for the audio source. Check to see they are each still in sync. You can use the encoding program to convert the audio to MPEG-1 Layer2 or better, AC3.
Put both files into your authoring program and it will set them to play one after the other, seamlessly. No joining.
If either of the files are corrupted, which is common if you were downloading them, then that may be the source of your sync problem. A lot of people have problems because there are a lot of bad files out there.
You need to check the sync each step of the way, even with the authored DVD, before you burn it.
MP3 VBR audio seems to have more sync problems than it's worth, IMO.
If your problem is different, you should start a new post.
