Well the shark codec does, at least make the thumbnails pictures, but none of Digital Video Repair, Avidemux, VirtualDub, or Free will open the files. The only one that produces a reason is Virtual "MPEG Import Filter: invalid packat position 71:marker not set; possibly Mpeg-2 stream"
. I did download an add that, trusting it was the right one, should have solved any MPEG-2 problem, but it would not extract into the main program as zip file reported invalid.
EDIT: I had a look at the thumbnails enlarged and from the look of it they are low res sort of duplicates of various jpgs taken on holiday in Majorca. How those MPG came in to being
Sorry for time wasted and thanks for your patience.
