Unable to scan music library in new installation

[Jack42]

I have just installed a MinimServer on an iMac (21.5 inch, Mid 2011, processor 2.5 GHz Intel Core i5, Memory 4 GB 1333 MHz DDR3, disk is 500 Gig HD) The music files are the contents of the iTunes Media folder copied to /Users/<my name>/ripped. I was unable to get MinimServer to read them in situ so I copied the files to the ripped folder. When I started the scan I got the following:

MinimServer[Johns-iMac.gateway] is running

I know that the files are correctly formatted because I can play them all using iTunes. The problem appears to be repeated spurious messages saying "Unexpected end of file". I assume that either I have mis-configured the server or that there is a bug when reading iTunes ripped files.

Can someone point me at the appropriate resource to get the issue resolved?
