[MPlayer-dev-eng] Another SiS vidix issue

[Jake Page]

Hey,

For the CRT1/CRT2 issue try setting the environment variable VIDIX_CRT=2 -
since the SiS 650 only has 1 overlay, it will tell the driver to use it 
on CRT2 if both video outputs are being used.

I looked a bit at the problem with the Martix trailer - I think there is 
an issue with large horizontal values in movies ( > 1000).  I also noticed 
that it has problems with "weird" aligned horizontal values, ie. 200x150, 
1000x500.  I'm probably not dealing with the source pitch alignment 
correctly, gotta track down where, though.

I'm not sure about the KDE/terminal corruption.  Maybe "offscreen" memory 
is being used for the alpha blending/blitting, and is being overwritten by 
the VIDIX driver using the same mem for the overlay?  The VIDIX 
framebuffer "memory management" is pretty hacky in general, doesn't 
necessarily play nice with X drivers.  I think the xvidix driver is a 
great way to test VIDIX development, but Xv is a better option for real 
playback, since it's better integreated with X11.  I'm primarily 
testing/using VIDIX on the framebuffer right now.

Thanks for the feedback!
