Problem Encountered
Whenever a video is pulled up in the content it is attached to, the thumbnail attempts to be re-generated, even though an adequate copy already exists. See screenshot.
Note that the thumbnail name keeps advancing by +1 on the end of the sequence.

Expected Behavior
When a video is displayed or retrieved for the content it belongs to (for editing), an existing imagecached thumbnail will be used, or ... a new one will be generated.

How many screenshots have you requested to be generated in your settings?

Are there any error messages in your Drupal log?

Could you also answer my other question too? Are there errors in the Drupal error log.

Yes, I keep finding "file not found" errors in the error log for video thumbs.
The files folder and the video_thumbs folders are fully writable, so i'm not totally understanding when this happens.
Here's a log entry:

No errors related to a transcoder failure?

Could you turn on "Log all executed commands to the Drupal log" and report the commands that are executed and the output?
