Green screen video issue (case 2626)

I'm having serious difficulties with 2 videos (.wmv) playing consecutively. The first seems to play fine, but the second video is small, green, and displays in the left quadrant (instead of centered on the entire screen). We have quit the program, restarted the computer, etc. The glitches are completely random and do not always happen on the same videos or trials. We are using Direct RT v2012 on Windows 7.

We really need to have this fixed before we can run study participants, so any help would be appreciated.

Can I provide any assistance with the issue on playing videos using DirectRT?
