I am using easydivx (freeware) to encode video but I keep getting the same error message audiodec has caused an illegal operation and will close down. When I check the completed files the video file will run but without sound and the sound track is contained in a seperate mp3 file. I have downloaded and installed all the codec but the problem remains. My system has an ATI Expert graphics card and I have disabled the onboard sound and installed a EDIO Hi-Live sound card. Any ideas where I am going wrong.
