I've converted several files with no problems but I ran into 1 file and when I tried to save it, it told me I needed to have Perian installed for the audio. Downloaded Perian and installed it but now I get a "Audio converter error:The audio converter cannot be initialized". I go back and turn off (says uninstall) Perian and I get the prompt that I need to download Perian. I've had Perian installed before and seems to be a pretty legit program but it seems kinda flaky. Am I just doing something wrong?
