I've shooted recently a 5 minutes Video using "12/15 GOP 'DREWnet' " on my gh2. As soon as I try to copy the file from the SD to my HDD, it freezes at a certain point. I am able to playback the video on the sd card, and I discovered that at the middle of the Video VLC freezes and crashes, therefore one frame must be damaged. I've tried several things (I am on Windows 7):

run chsdsk /r on the sd card (its freezes too), mpeg sptreamclip (can not open it), convert the footage in premiere and After effects, but while converting the programs crash (no respond), I tried to run testdisk (but as I did not delete the file, it didnt recover it), transcoding with 5DtoRGB freezes at the exact spot where VLC crashed, Converting with Adobe media converter also failed, Virtual Dub doesnt open it.

Is there any chance to copy the files at least as chunks? The file is 3,6 GB big
