The Sony Cybershot DSC-H50 is a still image camera, and still images don't have "PAL" or "NTSC" designations -- that's only for video.
According to dpreview.com
, this camera shoots video as MPEG-1, 640 x 480 @ 30fps silent (or 16.6fps with audio) in "fine" mode, or 320 x 240 @ 8.3 fps in "standard" mode. Unless they have missed something, I see neither NTSC (29.97fps or 23.976fps) or PAL (25fps) shooting speeds. It appears to be non-standard computer-only 30fps video anyway. That's if they even shot some video.
The video and images are saved on a Sony-proprietary Memory Stick Duo (or Pro Duo), and given that even 4GB cards cost about $30, I doubt either you or your friends want to go to that expense. Simply have the images copied to a blank CD-R or DVD-R/DVD+R and share that way.
That explain it?
