I'd be interested to know if the SD card works.
I deliberately bought an MMC card as this is what is specified in the manual (MMC is the precursor to SD, typically MMC cards work with SD readers, but not necessarily the other way round, so good luck). The manual (or at least my manual) doesn't specify a size, so I bought a 4GB MMC card, however if I stick more than 2GB on it it doesn't seem to pick everything up so a 2GB card is probably money well saved.
Also, you'll need to format the card in FAT (not FAT32) otherwise it won't recognise it.
