I have a Canon A85 that outputs avi files with mono audio. If I use DVD Flick to process the files to DVD format, it chokes on the audio - in that case I have to extract the audio and use the likes of 'Foobar2000' to convert the wav file to mp3, then add the mp3 to DVD Flick. On the other hand, there is a program called 'FAVC' which accepts the AVI and converts to DVD without complaint. http://www.afterdawn.com/software/video_software/dvd_tools/dvd_flick.cfm http://www.videohelp.com/tools/FAVC
