When trying to use the preview function with .avi-files everything went fine.
ok, the build-in player won't play them to 99,99 %
OD said, this can be configured in the settings, but I'm to less in knowledge to do this.
So the files will be opened with VLC or VirtualDub.
When now trying to seek ( or saying <play forward> ) it is horrible slow or undoable, which means waiting for an hour.
Can you please update the avi-preview-files with the necessary index ?
