I'm playing around with 2-19-2009 CVS on NT4 and I notice this error in the console:

"SDL_Init: Starting up with SDL windib video driver.
Try to update your video card and directx drivers!"

heh...well there's no way this driver is getting update ever!

Mabye it should be rephrased?

"Reverted to WINDIB due to old and/or buggy video drivers".

DOSBox seems to be working fine btw. Only issue I had was to use either overlay or opengl since ddraw/surface would not set the resolution back correctly on exiting DOSBox. (Not sure if this is new behavior or not).
