@archebyte, there is a graphical launcher for mplayer (sib) that hides the CLI.
I have voted for making CLI-only apps available only through apt. My understanding is that, as soon as there is a graphical interface available, the dependency will be solved? E.g. when launcher for the mplayer (graphical) appears in Application Manager, it won't bother the user the go to the terminal and install mplayer separately.

I think that this approach is consistent with the future of the Maemo platform, that will be mainstream (need for consistent user experience) but open to those more advanced users at the same time (go and install from terminal if you want).
