Hi Rog,
Try this link;
http://www.panasonic.com/consumer_electronics/sd_audio/downloads.asp It works with 1gig cards but only has a default playlist.
The good news (?) is that Panasonic are now on the case - or at least they say that the support people have passed the problem to the factory to fix. Which seems to be an admission from support that there is a problem with SD Jukebox.
If I hear any more I will let you know.
Cheers,
s.
