I found these difficult to find, hope useful for others : The Sony SxS drivers required for #xdcamex on MacBook Pro after Lion upgrade:

Did this work for you.
Have not upgraded to LION until everything works with EX-1.

Hi Bob - I only got as far as installing the new SxS driver, popping an SxS card into MBP and starting XDCAM EX ClipBrowser 2.6 (the pre-Lion version that I already had). The SxS card mounted fine and I could see the clips. Haven't transcoded them to mov and edited, but assume that will all be ok.

Please keep us updated. I'm especially interested in knowing if they release a new Final Cut Pro Log and Transfer utility. (it would be really cool if they released one for FCPX....but I'm just dreaming) :)

Hi - SxS drivers installed on MBP and MacPro with Lion. XDCAM EX Clip Browser and FCP 7 both working normally.
