I think maybe the version of Unity in the last version was more forgiving of codec issues than the new version. I'm still getting crashes in the latest version and I never saw any in previous versions (with the same girlpacks). I got text boxes in previous versions when it either didn't find or didn't like a video but no crashes. Maybe it's just me since I haven't seen other people complaining about crashes. Maybe I have one pack in particular that it doesn't like. Will have to play around some more I guess.
