I bought the avid book copied the MediaFiles to my imac on board hard drive but when i try and open projects it still looks to the dvd that came with the book. i took the dvd out and all the clips went offline.
sorry this is such a beginner question. ive looked online and cant find info about it.
That folder should only contain the .mxf files. Also note when copying projects (or any file) from a CD/DVD that they are locked. Just "get info" or properties and be sure to allow changes and all that good stuff.
Once you launch Media Composer, it should re-index itself and link.
