Embedded sound is not available at the moment. As for the tape name, that is dependent on the setting on your Settings page. It's not very self explanatory or even logical, but the setting for "assist using tape names from:" section actually assigns the tape name based on that setting when you put clips into the media pool. So, for instance, if you set it to use the clip name and set up the formatting string correctly, it will set the tape name to be the R3D file name, and it will include that in any MXF file you export for that clip. You can also use the embedded header name, which will sometimes evaluate to the first four places of the file name, and sometimes to the entire file name. As I said, a bit obtuse, but pretty simple once you understand it.
