:oops: You're so right.
I apparently didn't read your question properly and more or less "jumped to a conclusion"
I'll make a billboard for myself saying:
"First put brain at work before letting fingers tap the keyboard". :P
However, I have occasionally come across your problem in the past with a few videos and I've always been able to rectify it using VirtualDub.

Whilst using "direct stream copy" for both audio and video, you can use the "auto skew correction" of the "interleaving" tab of "audio".
Maybe you have to fiddle around a bit first to get it right, but I've always succeeded. (And you do not have to do the whole video to try of course; just a short piece (with voice) will do to find out if the setting you're using is OK!)
Success!!
