I just got a Creative Zen V Plus, and I am happy to say it works great with amarok  on kubuntu feisty fawn "out of the box"

The only problem I am having is that nowhere in the configuration options for the MTP media device does it say anything about transcoding before transfer.  I have these settings for  "Generic Audio Player" and the iPod devices.

Is there anyway to get the same transcode functionality in the MTP device plugin?
