I have (just) noticed that a number of WMA files that I thought I had played successfully through this device no longer play. I currently have the device set as a Pioneer Network Audio Player, and it appears that the files in question are WMA VBR files encoded at the highest VBR quality - resulting in an identified bitrate of more than 320kbps. I have had a quick look at the configuration file PioneerN and it would seem to recognise this limitation, but I can't see any way to ensure that any such files are automatically transcoded down to an accepted bitrate.

Should any files which are identified as having a bitrate more than supported be automatically transcoded/downsampled?
If so, what am I missing - should I be using one of the other profiles?
