We have an application that started out using QuickTime and MCI (QT  
if available and it could open the file on Windows, MCI otherwise).  
This worked well until some students started showing up with some  
computers that would lock up when using MCI (any MCI, not just Rev).  
I think it was Dell widescreen laptops but I don't remember exactly.  
Unable to fix the issue with driver updates we ended up having to  
create an external that used DirectShow for playback of files that QT  
could not open on Windows.

This all happened earlier this year and there may be some new video  
drivers that address the issue on those laptops and your target  
audience may not even use them. Just something to keep in mind and  
test for if you go the MCI route.
