Since I upgraded from v4.xx to 5.0.5 (and now 5.1), any new files I add to the library do not have thumbnails generated. Instead, I just get the default filmstrip icon. All files added prior to v5 show their thumbnails correctly. I have tried running the maintenance with the relevant options selected. I wonder if this is an FFMPEG problem. I am running Mezzmo on Windows Server 2003. If I right-click on an item and select 'Get FFMPEG Information', it shows an error 'Redirect console error: 5'. I would be grateful for any suggestions. Thanks.
