the dev files in this package are for the jreceiver rio client. basically what you do to use the jrec rio is untar the receiver.arf (from rio), delete the contents of the dev folder and unzip the rioboot dev.zip into the dev folder. when i do this, it works. when i delete the contents of the default folder and untar the rioplay receiver.arf file, the nfs log gets stuck on the dev folder contents.
