Hi I don't have a macontosh, but I recommend using bootcamp and emailing microsoft letting them know you are going this route so it does not interfer with your Mac OS operating system files and that you get the proper updates. Anyways I am sure there is a program for macontosh that will let you compile a win32 application or even service that lets the user switch kernels or just basic ones like directshow. You may also contact quicktime since they are that main base for filters and plugings involving trailers and their studio releases for mac. It might seem like to too much trouble and the easiest way is probably to recompile a program, so all you need to do basically is pick out the main dll files and extensions then let the process convert. Sony does this all the time with their ps3 to psp ps2 games.
