There were plans to implement empeg-download capability into the Central, but it was never developed or implemented. Only a limited number of Rio portable FLASH players are supported.

Short of an open-source implementation of the Central software, you are out of luck.

I currently rip on Central, upload to PC using jEmplode (USB+ethernet adapter), download from jEmplode to empeg (ethernet). I can only do this with my Mk 2, as I was not able to get USB going with jEmplode.

Incidentally, AVG is now marking the jempeg.com site as a drive-by malware installer. Has anyone maintained contact with Mike Schrag?
