Sansa m240 not recognised by Sony DVD recorder

My Sansa m240 when plugged into the USB port into my Sony dvd recorder (in both Auto & MSC modes) shows the word “Connected”, but it is not recognised by the dvd recorder - Is there any way round this? I tried an older (not Sansa) 256kb mp3 player and that worked. i would prefer to use the Sansa as it has a much higher storage capacity.

Thanks in advance for any suggestions.

Mine (mis)behaved the same way until I went into the settings and changed it to MSC instead of USB. Somehow the connection had changed, and nothing on my computer would recognize it until I set it back to MSC.
