OK, I've created the debug logs, which are attached. There are 3 logs, all from the same computer:<br>
Deleting duplicate entries<br>
Adding 1 new video (mp4)<br>
Reopening OpenLP, which again has the duplicate entries
With each log, I only performed the tasks indicated, didn't play any media, didn't add items to the service, etc. Just in, make the changes and out.<br><br>Please let me know if providing my database or other information will be of help. Thanks for looking into this, I'll be happy to help in any way.<br><br>
