iPad Camera Connection Kit not showing valid MP4 videos I've been wondering if I can use the camera connection kit as a way to directly copy video files onto my iPad for watching, from SD card. I've tested that photos and videos taken on my digital camera do show up on the "import" screen, but when I copy a different MP4 file (an episode of a TV show) into the exact same DCIM directory on the SD card, it is not visible for import. The MP4 was created specifically for iPad using HandBrake - I know if I import into iTunes library they will work on the iPad because I've been doing that already - but I'm going away and won't have my Mac with me.

Are there possibly file size restrictions in place, or something else I can easily fix?
I found the answer to my own question - the filenames must be in strict 8.3 format i.e. the main name is exactly 8 characters long.
