Your audio sync problem is related to a capture problem with Kona and FCP and Tiger…There is a workaround!!!
Unfortunately you can not batch capture but you can capture each clip as it is logged and the audio will be in sync..I am currently working on an HD movie shot at 23.98..I have successfully captured 800 clips so far…ALSO..I changed my device control offset to -3 (AJA swears that is should be -2.5 but I checked and their -2.5 offset will leace a 1 frame discrepancy between the tape TC and what FCP thinks the TC is…Other than this capture problem The KONA 2 seems to work in Tiger with FCP studio…Hope this helps your capture problem
