Crashing on import XDCAM (transfer)

Hi folks

I'm running OSX 10.5.8
Media 100 Suite 1.5.1
Sony XDCAM Transfer 2.11.0

trying to import directly from the cam into a M100 bin. Works okay for the most part. However, some clips cause M100 to lock up giving following warnings/error codes:

Program Error - 2014

and

M100 Unrecoverable error - 19524 (with a whole bunch of params and stuff)

Any clues? Weird thing is sometimes I'll try the same clips and they'll import okay. SOmetimes I'll restart the computer and hat fixes it for a while also. But ultimately it'll get to another clip at some point and it does the same thing. Seems to be quite random.

I now have to import a clip at a time because if I set it to import multiple clips and walk away 99% of the time it locks up and none of the clips get imported/saved - arrgh!

Any help would be appreciated.

Cheers
Paul
