Every time I try to play clip preview on a project, I get an error like memory could not be read or written
The preview start correctly and I have the error 1 or 2 seconds later.
For information, it was the same with UVS10+. I'm not sure but I think this problem has something to do with WMP11 codecs, because before installing it I never had this kind of error. Any ideas ?
Error like memory could not be read (yes it's in french):

or memory could not be written:

UVS11+ version 11.5.0.1.57.1 Plus
Source files properties: jpg & mpg less than 2Mb
Project properties: DVD PAL 720*576 - Stereo
XP SP3 FR + IE7 + WMP11
