One station broadcasts with a decreased volume. I record on TiVo and use kmtttg to retrieve and encode it so I can watch it on one of my iToys. Is there a way to use this product or a plug-in to increase the volume during one of the steps in this process?

For an ffmpeg profile you can simply add -vol # ffmpeg option to boost volume. See:

Thanks! I look for -vol and -volume in the ffmpeg documentation and do not see it defined. What value should I use?

I read here: http://forum.videohelp.com/threads/352067-normalizing-audio-volume-using-new-ffmpeg-options that ffmpeg "-vol" option is deprecated and ffmepg has new audio options, e.g. http://ffmpeg.mplayerhq.hu/ffmpeg-filters.html#volume but I am not clear how to use the command.
