Anyone test if EX1 footage shot on SDHC (using MXS adapter) will be readable in new MBP SD slot. I am at an Apple Store right now trying to test it, but card is not showing up. HELP please. Thanks

You probably have to install the drivers from Sony, the same ones as for SxS and then the transfer and clip browser as well to get the MBP to see the card.

Be very interesting to see confirmation of this.

If they did not use USB as the bus protocol between the card reader and the internal architecture of the machine then the data will NOT be transferable. If that is the case then all you need will be a USB SD card reader.
