Seems like mplayer wants a terminal to do its things, you know, like this
line

  A:   8.6 (08.6) of 334.0 (05:34.0)  0.8%

which it keeps updated constantly. It needs a terminal to update data on
screen (the notion of a "screen" basically implies that there is a terminal
involved). If you use FOR READ, Gambas connects the mplayer process to a
pipe which isn't a terminal.

Try FOR INPUT instead, which will create a pseudo-terminal, and see if that
is enough for mplayer.

Tobi
