Hi, Larry or Rob. I just tried the compression feature. Pretty neat. My question or concern is this. I seem to remember that we were told to check send files as music so we could navigate through the files better. If we uncheck this, will the navigation keys function as well as they do when send as music is checked? If it is unchecked, how do the navigation keys function as opposed to when it is checked? If I check send as music, I don't get the audio options. Thanks.
