What its telling you is, if you wanted to make a new AVI, then you would need to recompress with a constant bitrate, but since you are not interested in this, you only need to save the WAV file uncompressed, then it will be just fine for use in TMPGEnc.

If you save out the WAV without changing anything, it will be no use... So....

In Vdub, select Audio > Full processing mode
Now select Audio > conversion
Change the sample rate to 44.100Hz, leave the rest alone.
Now click File > Save WAV

The will now save out a large uncompressed WAV file, ready for TMPGEnc.
