My brother is running Ubuntu 10.04. He wants to be able to take movies captured using his Playsport Kodak camera off the camera, and then put them back on when he wants to play them on the TV. The device has a high speed SD card. He can't do it. Now, I have the same camera, so I can experiment. OK, I plug the camera into my Mac, pull the movies off, reformat the card, copy the movies back onto the card, and they play fine on the camera. Now, trying the same thing with my Ubuntu 10.04 box, I can copy the movies off into Ubuntu no problem. Then I reformat the card and try to move the movies back on. No go. Looks like they are copying, but it is choppy to copy and slow. Once completed, the movies do not show up as playable on the camera. What is the story here?
