Not only was it not downloading videos from my wife's camera, it has APPEARED to be downloading them because it grabbed the thumbnails from said videos. And it deleted them all off the drive transparently even though it didn't download them.
Gee -- let's delete .MOV files that haven't been downloaded without any kind of warning. Genius.
I whole-heartedly recommend Windows Live Photo Gallery. Not only is it generally better, but it doesn't lose your data transparently. And it can plug into Smugmug, Facebook and any other service you want to upload to.
