I have just uploaded a new version of HandBrakeBatch to the application feed. If you have activated the automatic update you will get a notification and this time the update process should work fine.
I have added a couple of Growl notifications, and the possibility to add files to the queue by dragging them on the application icon (either in the Finder or in the Dock). This is particularly helpful if you use applications like LaunchBar, now you can simply select a bunch of files, send them to LaunchBar, and open them with HandBrakeBatch.
As usual, all feedback is welcome!
