I just bought an RH-910 and have been trying to figure out this SS. I have transferred a number of files to MD but when I go to play them on the MD I get "Cannot Play Track" or something like this. This is only on a few tracks which I'm sure are bitrates not supported. I have had a similar issue with some podcasts I have transferred. I know that they are unsupported bitrates prior to uploading but isn't SS supposed to automatically convert unsupported bitrates? I have checked the options and it appears I have this option chosen.
