When listening to songs on sites such as slacker.com, the songs are streamed in mixed formats, i.e. some stream in .mp3 while others stream in .flv. Of course, my most natural preference is to keep the .mp3 files in that format but to convert any .flv into the .mp3 format. I know the manual workaround is to select any .flv files and convert them on-demand with a right-click--a simple but tedious process. So my question regards the automatic Conversion Settings in the following scenario: If I default Conversion Settings to MP3 High Quality, is RMC 4.1.6.0 intelligent enough to ignore--not convert--any song streamed in its original .mp3 format, and only convert those streamed in the .flv format? Or will it convert anything into .mp3 format regardless if that file is already in the .mp3 format?
