Jim,
A quick question – did you ever try the Vegas pro ‘Device Explorer’ way of importing the clips off the memory card from the HMC-150?
I regularly shoot on 32GB cards and create >4GB clips. The ‘Device Explorer’ can see a card reader and will stitch the clips automatically when importing.
Gilles and I had a very long discussion about this and tested a ‘stitched’ clip ~12GB vs clips just butted up against each other in Vegas and there was a major audio dropout using the second method. None in the stitched, large file.
Cheers for now,
