Thanks this was my fear of using MCI controls. apple seems to do a  
good job of making sure it plays with most graphics and audio chip  
sets so that these drivers issues are not too much of a problem. Hate  
to get into having to do a lot of tech support with folks w/o  
quicktime on PCs. When we require QT and they have it successfully  
installed we have zero tech support (big thumbs up for Rev and QT!)  
In the education market you dont make the big bucks to support tech  
support like this, let alone the development time necessary for a  
split development process like this so it may not be in the cards to  
try this. May poke at it some to see how good/bad it works in general.

Thanks again for your experience with it!
