sorry, here are the facts from long-testing period :
a/ the best libquicktime is still the 0.9.1, but it has big memory leaks, especially if you switch your movies very fast. after a while, of course, it will crash
ok indeed pd just died in my arms after 1h45 running 4 instances of this patch and directories with a lot of movies ... eating all the available memory until nothing left then ... rip...
