[Mplayer-users] can't initialize video driver

[Douglas Epperson]

Ok,

I'm stuck again

I try and launch a basic .mpg and get the folowing error:

+++++++++++++++++++++++++++++++++++++++++++++++++++++++
Couldn't open /dev/mga_vid
FATAL: Cannot initialize video driver!
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

When I compiled the driver I got the following output:

Does anyone have any suggestions?

I tried to search the dicussion board but the search wasn't working so I'm
sorry if this may be a repeat question.
