The computer that runs DirectRT uses Windows XP Professional and the version of DirectRT we're using is version 2008.1.0.11.
We tried the suggestion of making the colour.txt file and specifying the color bits, but instead of fixing the glitches, it affected the text files we have to display the instructions before presenting the videos. The videos still appears green with a shrunken ratio and the display of the instructions has been altered by the colour.txt file. The display of the instructions went back to normal after i deleted the colour.txt file but the glitches are still there, with the file or not.
We do not have the .drt files in our folders either.
As for trying on another machine, we are waiting on trying to run the same DirectRT session on another computer as you have suggested that we do. In the meantime, what can we do?
