Just finished upgrading this site. The upgrade went well on my test server and fortunately it also went well here. There was some odd issue with phpMyAdmin's backup though.
The offset for the next turn wasn't adjusted. Now it uses arrays and replaces the the whole lot at the very end. Well, weird code leads to silly mistakes. ;)
I checked out the Video module for Drupal, but it doesn't really look like what I need. I prefer a 1:1 mapping for screencasts, which allows you to read menus and dialogs easily. Youtube doesn't really cut it.
