Description Kevin DeKorte 2008-04-12 07:17:45 UTC

Using Keith's new textured video code from git as of 4/12 I found the following.

From a fresh boot

using mplayer play a video with one colorspace ie 
http://images.linspire.com/file_types/pinguin.mpg

Then play another file that comes up in a different colorspace

The second video will have a red or green tint to it.
The overlay port does not appear to have this issue
The more videos you play the worse it gets and after awhile all mpeg files playback with color problems.

my hardware is a G35 chipset

Ok, this one breaks for me too.

I've stuffed a kludge-around into the driver that replicates all of the source surface and sampler state. No, I don't understand why this helps, but it cleans things up for me at least. Please test and re-open if it still breaks for you.

Appears to be fixed for me. Nothing like using a sledgehammer to fix a small issue.
