First number is the black level,
Second number is Gamma,
Third number is white level,
forth number is what you want to adjust black level to,
fifth number is what you want to adjust white level to.
It's still washed out? Hmm, those numbers worked for me. Glad to hear you got to work though.
Also a handy tool you can use to check the color points is CSamp. Run the cursor over the frame while you have it opened in Virtualdub.
