Thanks Aud, but it didn't work. SD Jukebox still said "different file system format the card" even after formatting in the keyboard, then naming the card and its first folder.

RealOne Player Jukebox couldn't see that it was formatted either! I guess I am stuck with formatting and transferring audio in RealOne and using the default playlist this creates.

Strikes me that it is a bug in SD Jukebox. I have contacted Panasonic about it but have had no response yet. The Panasonic site says that the KN2600 and KN7000 are compatible with 1gig SD cards so you would think that they would make sure their software worked with them too!

At least we have RealOne, but it is second best.

Cheers,
