XDCAM EX SxS Cards will give Kernel Panic under Snow Leopard.

Question

In my conversation with Sony support they advised me that unfortunately
Snow Leopard is not currently supported by the current versions of XDCAM
related software's from Sony.
Since this is a very recent release from Apple that involves significant
change to the Mac OS it may take several months, perhaps winter or
spring for full Snow Leopard support from Sony. The exact schedule is
still TBD.
It is therefore recommended to continue using the most recent release of
Leopard to maintain smooth operation of the XDCAM software within the
Mac environment.
For your reference the latest Sony software release versions are as
below:
As of August 26th 2009
PDW-U1 v 2.420
PDW-U1 Utility for PC or Mac v 2.21
FAM Driver 2.20 comes with the PDZ-1 software or XDT for Mac
PDZ-1 v 2.60
XDCAM Viewer 2.30 PC only separate from PDZ-1
XDCAM TRANSFER for FCP v 2.10.0
EX Browser 2.5.1
Thanks for your continued support of XDCAM!

Answer 1

The best solution to the thumbnail issue seems to be to abandon XDCAM Transfer altogether until Sony deigns to offer a version compatible with Snow Leopard, and use Log and Transfer within Final Cut. You must instal the Sony plugin downloaded from here:

I discovered this after downgrading from Snow Leopard so as to keep working without having to manually import every shot... but have since re-upgraded to Snow Leopard, and everything works fine as above.
