I have a Sony HD Cybershot TX7 with PMB software V5. Does anybody know what video file type to load videos back onto the camera from a PC? The documentation is woefully inadequate, and just says some files produced on other cameras may not work. I have been trying every variation on MP4 files I can get my software (Corel VideoStudio Pro X3) to output, but PMB either doesn't even recognize he video file as valid, or the export function won't write it to the camera. Closest I got was MP4-H.264 in 320x280 which loaded to the camera but gets "File error" when you try to play!
