Hey there,

first of all, thanks for this great script! Saved me a lot of trouble =)

Just a short question: why is it that the created AC3 track is so much quieter than the original DTS track? (or is it just me..?) Is there a workaround for this because it can be kind of annoying if you switch the tracks.

Greetings!

There might be a normalization or an amplification option we can experiment with within ffmpeg. I will try to muck through the ffmpeg man pages and see what I can find.

One other thing, I just want to make sure you guys are using the latest 1.6 version of the script? We switched from aften/dcadec to ffmpeg when going from 1.5 to 1.6 and it might have something to do with that. It will be helpful to know which version you are using so we can isolate the app that is causing this.

Oh and did we mention that neither Jake nor I actually USE this anymore so it makes it tough to do some of the testing.
