Video players crashes on atiu9pag error using lucid MVP

I am using lucid MVP in "I" mode on a Gigabyte GA-Z77X-UP4 I7-3770K with a HIS ICQ AMD Radeon 7850 videocard on Windows 7 x64 Ultimate. Both Windows Media Player and SplashPro EX sometimes crash when starting to play an mp4/mpeg/DVD video. If I try to play the video again, it works fine. If the atiu9pag .dll is part of the Radeon software, I don't know why it is trying to use that since I am in "I" mode. Thank you.
