Input of code numbers

[jdv]

I have a DVD that has several videos on it. Two play with no problem. When attempting to play the others a code number
is requested. It is not recognised however, but if the DVD is played in a video recorder all videos play since the code number is input via the video controller. How do I trick the software into thinking keyboard number input is from a video controller?

As far as I know, DVD menus do not use digits, only the arrow keys (and/or the mouse pointer). So your question does not make much sense to me.

If it really is a DVD, you can view the video anyway: just select the correct title in the Playback/Navigation menu.
