Did the thumbnail/previewing ever get fixed?

I found a thread from December that was talking about problems with preview thumbnails in some files(causes Explorer to sort of hang on the preview and interferes with stuff once it happens until the explorer processes are killed off). It also looks like Haali has similar problems, but there is a offset setting in HAali that apparently will work around the issue in a lot of cases. Did it ever get resolved for the DivX MF splitter?

I can see previews in

I can see previews in Windows/Explorer, but not on my Xbox 360.
