I think this is actually a damn good bit of kit, but the software is awful!
However, after a lot of messing around with things I have got it to work.
The problem is with the id3 tags - the program is very fussy about how they are recorded. iTunes really messes up the tags, which is why I think most people have the problems with this software.
Anyway, to get it to work you will need to google 2 free pieces of software - Firstly "MP3 Toys" and secondly "MP3 Tag".
Download both of these and install them - then take a look at the video I have made and posted on Youtube.
I am not allowed to post the link, but if you search in youtube under "JukeMaster 100 Software" you should find it!
Good luck and I hope it works for you.
