Repairing a video clip thumbnail

[Sebastian42]

Amongst many video clips, SOME show only a 'generic' thumbnail FOR A PLAYER
rather than for the clip content. Make Video Thumbnails can extract JPGs from
(not all) the video clips with extensions like avi, mpg, wmv, swf, flv, etc. So then there are two files with the same name but different extensions (a JPG and a video-extension). How can the video clip file absorb the JPG so that the videoclip will show the image thumbnail, rather than the generic player thumbnail ?
OR - how can the original video clip be 'repaired' to show a content-thumbnail ?

Hi Sebastian
You one thumbnail has jpg under it this could happen if you have accidentally opened up with a graphics program or while editing you put a jpeg in with the video.

It's NO accident. My video clip lacked a thumbnail, so I created one. The probem is that it is a separate file, instead of the image on the video clip when set to view thumbnails.
