On certain digital cameras when pictures are taken you’ll get the image (usually .jpg, but could be .tif or raw), and a thumbnail (usually .thm extension). The thumbnail is usually tiny, and it’s just a (majorly shrunk) copy of the image (usually also in jpeg format), possibly with metadata in it. When you browse the pics through your camera, the list of preview pics you see are actually from the thumbnails (the camera does not read the whole original image until you actually open it - this saves time). The same thing happens when you have .AVI or .MOV recorded. They will be referenced by the camera via the .THM file.
While I don’t know what .MOI and .PGI are, it could be they’re thumbnails or metadata files, without which the camcorder can’t refer to the video file to play it back.
You could attempt to artificially create thumbnails or metadata files to force the camcorder to read your video. That’s risky business because I don’t know what exact information goes in those files. If it’s just a thumbnail with nothing else, I guess renaming any other thumbnail to match the name of the .MOD may work. If it’s more complicated, like it stores file size, playback length etc. then you wouldn’t want to mess with it. For example if you wrote a playback length that was too long it could try to read past the end of the file, with unpredictable consequences (data corruption, physical damage to media, who knows?) Bottom line is if you can salvage the file and you don’t absolutely need to play it in the camcorder don’t worry about it.
