I have a GH2 that recorded a full 16GB SD card of video clips. When offloading the card to computer, 2 of the clips reported errors that they cannot be copied and are corrupted - (0x80070570 error) .
However the clip can be played from the SD card in Windows Media player. (altho playback controls dont work) Whats the deal with this? What can i do? Any insight or user reporting this problem and a solution?

Problem solved: I removed SD Card and reinserted. Windows notified me there were file system errors, and i clicked fix errors. The files are now copyable.
