I don't even bother using the Sony software to transfer the files. I copy the raw *.MTS files from the camera to my hard drive. The only thing I can see the Sony software doing is it creates a dated folder and converts the files to *.M2TS as well as creating 2 additional files for each M2TS. To be honest, I'm not really sure what purpose these additional files serve. I have heard that if you film continuously for a very long time, the camera will automatically break it up into multiple MTS files. Not sure if the extra files are used to tie the multiple MTS files together during the transfer (using the Sony software) or not. Again not sure on that.
After connecting the camera with the supplied USB cable, I then turn on the camera and place it into USB mode.
After that, the camera behaves as just another external drive. I then browse to the folder containing the MTS files and copy them to my project capture folder.
Then I just open Power Director and using Windows Explorer, drag the desired files into the work area (Edit tab selected).
This has worked for me so far with no apparent problems.
Hope this helps.
Peace,
Dan
