Problems extracting VBR audio

[abilio]

I'm using VirtualDub/TMPGEnc to convert my DivX's to VCD, but in some movies, i facing to a weird problem. When i wanna extract audio VBR from any movie, i do the following: I check "Full Processing Mode" in Audio menu, and in Audio menu again, i go to conversion. In Audio Conversion Window, i check 44100, 16bit and no changes on audio. When it is done, i save the audio, using "save as wav" submenu, a file about 1gb of size. So, in some films the audio remains unsynchronized. How can i fix this problem?

Thanks in advance

That is all you need to do.
