Anybody know what the max capacity usb stick you can use ? Tried searching the web but can't find any info bar the fat format and sector size.

I've tried an 8 gig stick and there appears to be an issue. The music is there and plays ok but the album folders have the wrong track listings.
If I reformat it and re-sync with media player it works for a bit then starts again.

Works fine with 1 gig sticks.
