First VirtualDub's error is simple. The audio of that AVI file was compressed MP3 VBR instead MP3 CBR. I still haven't understood what is the 'rewrite audio header' point, but what philraz suggested you is correct. Selecting Audio__Full processing mode withount specifyng anything else will create an audio stream uncompressed WAV, that it without any 'improper audio encoding' problem.
The second error is more subtile, and I haven't understood how some AVI could have strange framerates (i.e. NOT 23.976, 25.000, 29.970).
The error:
different sampling rates(17862.00000 vs 17892.00000) [please note that 'sampling rate' is in ms, 'framerate' is in seconds, and therfore the 1000 factor] means that the sampling rates are different from a very little amount (which VirtualDub's cannot show, because the approximation is a ms), but exist, since VirtualDub detects them.
How to correct it? I really don't know, since I never found this error. You could try this way. Let's say your movies are named CD1.AVI and CD2.AVI.
1) open the CD1.AVI
2) select Video__File__File Information and write down the number (let's say 17.892 fps).
3) Open the 2nd AVI.
4) Select Video__Frame Rate
5) click on 'Change to [XXX] frames per second' and set XXX to the value you saw when you made File__File Information on the 1st movie.
Let's go assuming you set 17.892, as in your example.
6) set Video__Direct Stream Copy and save (F7) CD2_new.AVI.
If tha framerates is changed of a very small amount you won't advert any A/V desynchronization.
Now CD2.avi has a framerate of EXACTLY 17.892 fps (withount any decimal part).
7) Open CD1.AVI , select File___Append new segment and load CD2_new.AVI. It won't accept it only if the framerate wasn't exactly 17.892 (and therefore you have to create a new CD1_new.AVI as you made before whrn you transformed CD2.avi --> CD2_new.avi.
8) Once CD1.avi (or CD1_new.avi if the exact framerate wasn't 17.892)and CD2_new.avi have been loaded, set Video__Direct Stream Copy and Save (F7).
I hope it works.
