Trying to join 2 avis with different audio rates pls help

[targus]

Hi
Sorry if the general section is the wrong place for this Q.

I'm a complete amateur and only know what I've learned from this site - which says a lot for the info on offer as
so far I've managed to join several AVI's OK with virtualdub and encode/burn them to dvd with VSO but I've run into some trouble trying to join two AVI's today.

When I load the first half into virtual dub I get the message saying it has detected improper VBR audio encoding and that it will be rewritten with standards CBR valuse that may cause 6444ms of skew. It suggests decompressing the audio stream to a wave file and then recompressing it with a constant bitrate encoder.

If I click OK then try and append the second half it comlains that the two cannot be joined as they have different audio sampling rates 13877.00000 vs 13940.00000.

I should add that I just used Gspot and it shows the ausio as 0x0055(MP3, ISO) MPEG-1 Layer 3 / 44100Hz VBR 111 kb/s total
(2 chnls) for the first half and 0x0055(MP3, ISO) MPEG-1 Layer 3 / 44100Hz VBR 112 kb/s total (2 chnls) for the second half

Well thats me stumped.

I guess my question is...Is it possible to join the two halves by stripping out and re-encoding the audio and if so how - instructions for an ameuteur please.!

Any help would be much appreciated.

i tried search for virtualdub join:
https://forum.videohelp.com/viewtopic.php?p=1437011#1437011

but why join at all? just add all avis in divxtodvd and convert to one dvd...joining often cause sync problems.

Baldrick thanks for the reply. I used the new version of divxtodvd and hte result is ok, but it looks like it's created 2 movies that play as one. i.e when it goes beyond half way you cant go back and the chapter numbers and runnign time are reset. Does this always happen - I've always joined them first before.

Cheers

The ONLY way to fix it is for you to demux the audio, re-encode it as CBR, then mux it back in, and this may introduce sync error in itself. THEN there's still no guarantee that this will join properly.
