Hello, I couldn't really see another spot that might be more appropriate for this so here goes. I am programming for windows right now but plan to take it to mac eventually. I am trying to copy a music file over a movie file and lower the sound on the music before i do. My problem is that I picked up the project from where someone else left off and they were using quicktime 2.0 sdks. I have downloaded the 7.3 sdk from the apple site but I can not figure out how to add it to my resorces in visual C#. Is there anyone out there who can help me with either figuring out how to do it in 2.0 framework or how to add the 7.3 correctly? Thanks.
