Using AVStoDVD. Added a file got a caution that windows audio was set as the default, directed me to answered question that says I should adjust the Lav filetrs, using the AVStoDVD Directshow Codec tool. I can't find this to do this. I did find a Codec Tweak tooland tried to set the lav filetrs as default, as well as what I could find to set the lav filters, but the message still comes up. WHere can I find this Code toll so I can set the lav filters?
