Update: result is unchanged (no sound in .mp4 output) when downloading from a Tivo Roamio. Trying different profiles also has no effect. KMTTG must be broken because of some change other than tivo web server.
I just installed kmttg and am trying one tivo download to test the config. I also am getting a .mp4 output file with no sound while the .ts file in \mpg_out has sound. Also, download/save works fine using Archivo. My tivo is an old Premier XL that still works fine (knock on wood). I am guessing I have something configured wrong for the encode. Any suggestions would be greatly appreciated.
