bitpim & videos
in BitPim, click on the "filesystem" tab and click on the + next to "brew" and then that folder should expand. Then click the plus sign next to "media" and you should see some of your recorded videos with extensions as 3g2. If you right click any of these files and save them to the computer, you can view them on your computer using the newest version of quicktime.
But im still not sure if it'll let you upload if you simply place a video file in 3g2 format in that location.
