Watcha Bernie - what are you doing up at this time of night?...chuckle
Using SD Jukebox is pretty straightforward once you have made sure that all the set up info is pointing at the right files on your 'puter. At the moment it seems that the audio files which it stores and can sort into different orders for you only works on SD Cards up to 512mb with problems currently on the 1 gig SD Card which are being investigated hopefully.
My 512mb SD Card has about 170 songs stored on it for audio play on the KN7000, and it's pretty much full up...
