My first post here! I got a lot of music on my pc in WMA format (6-7GB), I don't want to spend a lot of time to convert them all to MP3 or AAC format for my new mac. I know there is a function in QT, which allow these files to be saved with reference file format, then I can import all these reference movie files into itune. Just wondering is there a way to make a batch to this "save as..." in one click? Any response will be really appreciated!
