I had started, a month ago, a thread "composite input a/v sync issue".
I managed to superbly digitize quite a few VHS tapes back then. It might suit your needs as well.
Take a look:

And,pls. let me know if the hack that it seems to me that you are using to digitize
the tapes (vlc capture, and then mencoder whatever...)... 
Pls. let me know if vlc+mencoder is a better solution, better quality, which I doubt, 
but I can't tell of course...
Namely, I am not and have not been converting tapes to files since back then, so I cannot test,
but I am curious to know...
Good luck!
