This has only happened to me on two occasions. For some reason, the FLA file for the Geoweasel episode "Fate's Fault" is corrupt, meaning a lot of things are missing (audio and visuals) when you load it, which is going to make this a tough one to get on the DVD, since I normally go in and edit the FLAs to change audio and output settings before converting the SWF. Oddly enough, when I look at these raw files with pieces missing all over the place, it looks like a totally different (and frankly more interesting) cartoon. Below are some screencaps of some of the corrupted stuff. Click on the images to see a larger version as well as a description.
