I am getting the same error as whotheff above..
the video freezes and i get windows alert error every 2 seconds, i cant close the program unless i ctrl alt delete and the program continues to lag the system, it takes about 30seconds to 2 minutes to try and close the application once this occurs, it happens usually when trying to rewind or fast forward with the arrow keys, it could be the first time you hit it, or the 25th time you hit it. Its unpredicatable and very annoying!!!

EDIT: I have been dealing with this error for 5 months now, ever since i updated to Windows 7, i was on XP SP3 and no error ever occured. I even used the same version on Win7, but i updated thinking it was an oudated error, nope i guess not!
