I'm having problems reading my SxS express card. I have video footage from a sony pwex3 and i slotted it into the port on the mac book and at the top right hand corner of the monitor it has a little pic of a video that comes up which means that it recognises it, but when I click it, it says mass storage controller but I can't select it. It also doesn't show up as a device when I go the finder. Is there some other program I need to be able to read this card? Keeping in mind that this mac book is about 2 weeks old and I have the bare minimum of programs on it. Any help would be greatly appreciated. Cheers.
