Thanks Len, it is interesting that the standard of SD cards seems to be so variable!

I am still baffled by the fact that the same card works perfectly with RealOne Jukebox. I thought this was virtually the same thing as SD jukebox. If it wasn't for the lack of user playlists I would give up on SD jukebox and just use RealOne.

The Panasonic site says that the KN7000/2600 are not compatable with 2gig cards. I wonder if that is an internal software or hardware restriction or an SD Jukebox feature.

Cheers,
